Question

4. (a) Construct 3 equations starting with x = 2
(b) Construct 3 equations starting with x = -2​

Answer 1

Answer:

1 question answer

3 equation starting with ×=2

1. ×=2

Multiplying both sides by 10, 10x =20

adding 2 both sides 10x +2 =20+2=10x +2=22

2. x =2

Multiplying both side by 5, 5x =10

subtracting 3 from both sides 5x -3=10-3=5x -3=7

3. x =2

Dividing both sides by 5

$\frac{x}{5} = \frac{2}{5}$

2 question answer

construct 3 equations staring with x = -2

x =-2

1. x =-2

x +2=0

2. x -2= -2 -2

x -2 = -4

3. 2x =2 × (-2)

2x = -4
