Question 1. Check whether the given value in the brackets is the correct solution to the below-given equation or not:

(a) n + 5 = 19 (n = 1)

Answer 1.:

LHS = n + 5

By substituting the value of n = 1

Then we get,

LHS = n + 5

= 1 + 5

= 6

By comparing the LHS and RHS

6 ≠ 19

LHS ≠ RHS

Hence we get that the value of n = 1 is not the solution to the given equation above n + 5 = 19.

(b) 7n + 5 = 19 (n = – 2)

Answer :

LHS = 7n + 5

Now, by substituting the value of n = -2

Then we get,

LHS = 7n + 5

= (7 × (-2)) + 5

= – 14 + 5

= – 9

By comparing the LHS and RHS

-9 ≠ 19

LHS ≠ RHS

Hence we know that the value of n = -2 is not the solution to the above-given equation 7n + 5 = 19.

(c) 7n + 5 = 19 (n = 2)

Answer:

LHS = 7n + 5

By substituting the value of n as = 2

Then,

LHS = 7n + 5

= (7 × (2)) + 5

= 14 + 5

= 19

By comparing both the LHS and the RHS

19 = 19

LHS = RHS

Hence, the value of n = 2 is the solution to the given equation is 7n + 5 = 19.

(d) 4p – 3 = 13 (p = 1)

Answer:

LHS = 4p – 3

By substituting the value of p = 1

Then,

LHS = 4p – 3

= (4 × 1) – 3

= 4 – 3

= 1

By comparing both the LHS and the RHS

1 ≠ 13

LHS ≠ RHS

Hence then, the value of p = 1 is not the solution to the above-given equation 4p – 3 = 13.

(e) 4p – 3 = 13 (p = – 4)

Answer:

LHS = 4p – 3

By substituting the value of p as = – 4

Then,

LHS = 4p – 3

= (4 × (-4)) – 3

= -16 – 3

= -19

By comparing both the LHS and the RHS

-19 ≠ 13

LHS ≠ RHS

Hence then, the value of p = -4 is not the solution to the above-given equation 4p – 3 = 13.

(f) 4p – 3 = 13 (p = 0)

Answer:

LHS = 4p – 3

By substituting the value of p = 0

Then,

LHS = 4p – 3

= (4 × 0) – 3

= 0 – 3

= -3

By comparing the LHS and RHS

– 3 ≠ 13

LHS ≠ RHS

Hence then, the value of p = 0 is not the solution to the above-given equation 4p – 3 = 13.

Question 2. Solve the following equations by the trial and error method:

(i) 5p + 2 = 17

Answer:

LHS = 5p + 2

By substituting the value of p as = 0

Then,

LHS = 5p + 2

= (5 × 0) + 2

= 0 + 2

= 2

By comparing both the LHS and RHS

2 ≠ 17

LHS ≠ RHS

Hence then, the value of p = 0 is not the solution to the above-given equation.

Let, p = 1

LHS = 5p + 2

= (5 × 1) + 2

= 5 + 2

= 7

By comparing the LHS and the RHS

7 ≠ 17

LHS ≠ RHS

Hence then, the value of p = 1 is not the solution to the above-given equation.

Let, p = 2

LHS = 5p + 2

= (5 × 2) + 2

= 10 + 2

= 12

By comparing both the LHS and the RHS

12 ≠ 17

LHS ≠ RHS

Hence then, the value of p = 2 is not the solution to the above-given equation.

Let, p = 3

LHS = 5p + 2

= (5 × 3) + 2

= 15 + 2

= 17

By comparing both the LHS and the RHS

17 = 17

LHS = RHS

Hence, the value of p = 3 is the solution given to the given equation.

(ii) 3m – 14 = 4

Answer:

LHS = 3m – 14

By substituting the value of m as = 3

Then,

LHS = 3m – 14

= (3 × 3) – 14

= 9 – 14

= – 5

By comparing both the LHS and the RHS

-5 ≠ 4

LHS ≠ RHS

Hence then, the value of m = 3 is not the solution to the above-given equation.

Let, m = 4

LHS = 3m – 14

= (3 × 4) – 14

= 12 – 14

= – 2

By comparing both the LHS and the RHS

-2 ≠ 4

LHS ≠ RHS

Hence then, the value of m = 4 is not the solution to the above-given equation.

Let, m = 5

LHS = 3m – 14

= (3 × 5) – 14

= 15 – 14

= 1

By comparing both the LHS and the RHS

1 ≠ 4

LHS ≠ RHS

Hence then, the value of m = 5 is not the solution to the above-given equation.

Let, m = 6

LHS = 3m – 14

= (3 × 6) – 14

= 18 – 14

= 4

By comparing both the LHS and RHS

4 = 4

LHS = RHS

Hence, the value of m = 6 is the solution to the above-given equation.

= p = 14/5

(b) – 4 = 5(p – 2)

Answer:

Let us divide both these sides by 5,

= – 4/5 = (5(p – 2))/5

= – 4/5 = p -2

Now by transposing – 2 from the RHS to the LHS, it becomes 2

= – (4/5) + 2 = p

= (- 4 + 10)/ 5 = p

= p = 6/5

(c) 16 = 4 + 3(t + 2)

Answer:

By transposing four from the RHS to the LHS, it becomes – 4

= 16 – 4 = 3(t + 2)

= 12 = 3(t + 2)

Let us divide both these side by 3,

= 12/3 = (3(t + 2))/ 3

= 4 = t + 2

By transposing 2 from the RHS to the LHS it becomes – 2

= 4 – 2 = t

4. 2x + 3 = 114

Ans

3. 2x + 2 = 114

Explanation

Let the two consecutive even numbers be x and (x + 2).
Given,
x + (x + 2) = 114
or, 2x + 2 = 114, which is the required equation.

Q.3 If an integer is 5 more than the other integer and their sum is 71. What are the values of these integers?

Marks:1
1. 30 and 41

2. 33 and 38

3. 35 and 36

4. 31 and 40

Ans

2. 33 and 38

Explanation

Let the first integer be x.
Then, other integer = x + 5
Now, x + (x + 5) = 71
or, 2x + 5 = 33

or, x = 33
The other integer is
x + 5 = 38
Hence, required integers are 33 and 38.

Q.4 Give one example of an equation whose solution is 5.

Marks:1
Ans

Let x = 5
On multiplying both sides by 2, we get
2x = 10
On adding 3 to both sides, we get
2x + 3 = 10 + 3
Or 2x + 3 = 13 which is one of the equations whose solution is 5.

Q.5 Set up an equation for the following cases:
1. The age of Kanika is four times that of her daughter. The difference between their ages is 27 years.
2. The interest received by Karim is 30 more than that of Ramesh. The total interest received by them is 70.

Marks:3
Ans

1. Let the age of Kanika’s daughter be x years
So, age of Kanika = 4x years
According to the statement, the difference between their ages is 27 years,
i.e., 4x – x = 27, which is the required equation.
2. Let interest received by Ramesh = x
So, interest received by Karim = (x + 30)
According to the statement, the total interest received is 70
i.e., x + (x+30) = 70, which is the required equation.
