MP Board Class 8th Maths Solutions Chapter 2 Linear Equations in One Variable Ex 2.1

Solve the following equations.

Question 1.
x – 2 = 7.
Solution:
We have, x – 2 = 7
Transposing -2 to R.H.S., we get
x = 7 + 2 ⇒ x = 9, which is the required solution.

Question 2.
y + 3 = 10.
Solution:
We have, y + 3 = 10
Transposing 3 to R.H.S., we get y = 10 – 3
⇒ y = 7, which is the required solution.

Question 3.
6 = z + 2.
Solution:
We have, 6 = z + 2
Transposing 2 to L.H.S., we get
6 – 2 = z
⇒ z = 4, which is the required solution.

Question 4.

Question 6.

Question 7.

Question 8.

Question 9.
7x – 9 = 16.
Solution:
We have, 7x – 9 = 16
Transposing -9 to R.H.S., we get
7x = 16 + 9
⇒ 7x = 25
Now, dividing both sides by 7, we get

Question 10.
14y – 8 = 13.
Solution:
We have, 14y -8 = 13
Transposing -8 to R.H.S., we get
14y = 13 + 8 ⇒ 14y = 21
Now, dividing both sides by 14, we get

Question 11.
17 + 6p = 9.
Solution:
We have, 17 + 6p = 9
Transposing 17 to R.H.S., we get 6p = 9 – 17
⇒ 6p = – 8
Now, dividing both sides by 6, we get

Question 12.
