## NCERT Solutions for Class 7 Maths Chapter 4 Simple Equations Ex 4.3

**Question 1.**

Solve the following equations:

**Solution:
**

**Question 2.**

Solve the following equations:

**(a)** 2 (x + 4) = 12

**(6)** 3 (n – 5) = 21

**(c)** 3 (n – 5) = -21

**(d)** -4 (2 + x) = 8

**(e)** 4 (2 – x) = 8

**Solution:
**

**Question 3.**

Solve the /bilowing equations:

**(a)** 4 = 5 (p – 2)

**(b)** -4 = 5 (p – 2)

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

**(d) **4 + 5 (p – 1) = 34

**(e)** 0 = 16 + 4 (m – 6)

**Solution:
**

**Question 4.**

**(a)** Construct 3 equations starting with x = 2

**(b)** Construct 3 equations starting with x = – 2.

**Solution:**

**(a) ****1.** Start with x = 2

Multiply both sides by 3, 3x = 6

Subtract 2 from both sides, 3x – 2 = 4 …(1)

**2.** Start with x = 2

Multiply both sides by 4, 4x = 8

Add 5 to both sides, 4x + 5 = 13 …(2)

**3.** Start with x = 2 Multiply both sides by 5 5x = 10

Subtract 1 from both sides, 5x – 1 = 9 …(3)

**(b) First equation:**

Start with x = -2

Multiply both sides by 2, 2x = -4

Subtract 3 from both sides, 2x – 3 = -7

**Second equation:**

Start with x = – 2

Multiply both sides by – 5, – 5x = 10

Add 10 to both sides, 10 – 5x = 20

**Third equation:**

Start with x = -2

Divide both sides by 2, \(\frac { x }{ 2 } \) = -1

Add 3 to both sides, \(\frac { x }{ 2 } \) + 3 = 2
