Question

(a) Construct 3equations starting with x = 2

(b) Construct 3equations starting with x = − 2

Answer 1

(a) x = 2

Multiplyingboth sides by 5,

5x= 10 (i)

Subtracting3 from both sides,

5x− 3 = 10 − 3

5 x− 3 = 7 (ii)

Dividingboth sides by 2,

(b) x = −2

Subtracting2 from both sides,

x− 2 = − 2 − 2

x− 2 = −4 (i)

Again,x = −2

Multiplyingby 6,

6 ×x = −2 × 6

6x= −12

Subtracting12 from both sides,

6x− 12 = − 12 − 12

6x− 12 = −24 (ii)

Adding24 to both sides,

6x− 12 + 24 = − 24 + 24

6x+ 12 = 0 (iii)
