Answer:
(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

3 equation starting with x=2(i) x=2Multiplying both sides by 10, 10x=20Adding 2 both sides 10x+2=20+2=10x+2=22(ii) x=2Multiplying both sides by 5, 5x=10Subtracting 3 from both sides 5x−3=10−3=5x−3=7(iii) x=2Dividing both sides by 55x=52
