**Download NCERT Solutions for Class 8 Maths Chapter 2 Exercise 2.1 – Linear Equation in one Variable**

**NCERT Solutions for Class 8 Maths Chapter 2 Exercise 2.1 , has been designed by the NCERT to test the knowledge of the student on the following topics : **

- Introduction
- Solving Equations which have Linear Expressions on one Side and Numbers on the other Side

**1. Solve x – 2 = 7**

Transposing -2 to RHS

x = 7 + 2

x = 9

**2. Solve y + 3 = 10**

Transposing +3 to R.H.S

y = 10 – 3

y = 7

**3. Solve 6 = z + 2**

Transposing +2 to L.H.S

6 – 2 = z

4 = z

z = 4

**4. Solve + x = **

Transposing + to R.H.S

x = –

x =

x =

x = 2

**5. Solve 6x = 12**

Dividing both sides by 6

=

x = 2

**6. Solve = 10**

Multiply 5 on both sides

x 5 = 10 x 5

t = 50

**7. Solve = 18**

Multiply both sides with [Multiplicative inverse of ]

x = 18 x

x = 27

**8. Solve 1.6 = **

Multiply both sides with 1.5

1.6 x 1.5 = 1.5 x

y = 2.4

**9. Solve 7x – 9 = 16**

Transposing -9 to RHS

7x = 16 + 9

7x = 25

Dividing both sides by 7

=

x =

**10. Solve 14y – 8 = 13**

Transposing -8 to RHS

14y = 13 + 8

14y = 21

Dividing both sides by 14

=

y =

**11. Solve 17 + 6p = 9**

Transposing +17 to R.H.S

6p = 9 – 17

6p = -8

Dividing both sides by 6

= –

p = –

**12. Solve + 1 = **

Transposing +1 to R.H.S

= – 1

=

Multiply both sides with 3

x 3 = x 3

x =

x =
