Question

i x +1= 20 ii 2x+5 = 45 iii 15 = 2x+13 iv 8(x-7) = 144 v 52 = 2(x+7) vi $\frac{7y}{7}$ = 1 vii 2 x - 1 = 11 viii $\frac{3x+3}{2}$ = 9

Answer 1

Answer:

i)x=20-1=19

ii)2x=45-50

2x=40

x=40/2

x=20

iii)15-13=2x

2x=2

x=1

iv)8x-56=144

8x=144+56

8x=200

x=200/8

x=25

v)52=2x+14

52-14=2x

2x=38

x=19

vi)7y=7

y=7/7

y=1

vii)2x=11+1

2x=12

x=12/2

x=6

viii)3x+3=9×2

3x+3=18

3x=18-3

3x=15

x=15/3

x=5
