(a)
(i) x= 2
multiplying both sides by 2
2x= 4
adding 2 both sides
2x+2 = 6
(ii) x= 2
mu;tiplying both sides by 5
5x= 10
add 5 on both sides
5x+5 = 15
(iii) x= 2
5 / x = 5/2
adding 2 on both sides
5/x + 2 = 5 / 2 + 2
(b)
(i) x= -2
multiplying 10 on both sides
10x = -20
addong 2 both sides
10x+2 = -20+2
10x +2 = -18
(ii) x=-2
multiplying 3 both sides
3x= -6
(iii) x=-2
multiplying 3 both sides
3x = -6
adding 7 on both sides
3x+7 = -6+7
3x+7 = 1
