Question

2x = 7 ,construct three equations​

Answer 1

Answer:

3 equation starting with x=2

(i) x=2

Multiplying both sides by 10, 10x=20

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

(ii) x=2

Multiplying both sides by 5, 5x=10

Subtracting 3 from both sides 5x−3=10−3=5x−3=7

(iii) x=2

Dividing both sides by 5

5
