Answer 1

A)3x-3=x+4
3x - x = 4 + 3
2x = 7
x = 7/2

B)8x+4=6x+10
8x - 6x = 10 - 4
2x = 6
x = 6/2
x = 3

C)3x=27
x = 27/3
x = 9

D)x/5=-13
x = -13/5

E)5x+2x=6+8
7x = 14
x = 14/7
x = 2

F)x/8=27
x = 27.8
x = 216

G)3x=81
x = 81/3
x = 27

H)9x-2=5x+11
9x - 5x = 11 + 2
4x = 13
x = 13/4

I)9x=18
x = 18/9
x = 2

J)4x+5=25
4x = 25 - 5
x = 20/4
x = 5

M)5x-7=3x-12
5x - 3x = -12 + 7
2x = -5
x = -5/2

0)x/6=15
x = 15.6
x = 90

P)6x-9=123
6x = 123 + 9
x = 132/6
x = 22

Q)8x+4=2x+19
8x - 2x = 19 - 4
6x = 15
x = 15/6 = 5/2

R)3x-6=x+4
3x - x = 4 + 6
2x = 10
x = 10/2
x = 5

S)x/2=110
x = 110 . 2
x = 220

T)25x=125
x = 125/25
x = 5

U)3x=36
x = 36/3
x = 12
