Answer 1

a)7x-7-2x+10=x-5
5x+3=x-5
5x-x= -5-3
4x= -8
x= -2

b) 6-2x=3x-12+15
6-2x=3x+3
-2x-3x=3-6
-5x= -3
x= 3/5

c)15-3x-3+6x=42
12+3x=42
3x=42-12
3x=30
x=10

d)8x+12-2x=x-6+10+14
6x+12=x+18
6x-x=18-12
5x=6
x=6/5

e)4x-12-x-2+2x-2-5= 0
5x-21=0
5x=21
x=21/5

f)3x-8x+6=2-3x+3
-5x+6=5-3x
-5x+3x=5-6
-2x= -1
x=1/2

g)3x-1-x+3+5x-10=18
7x-8=18
7x=18+8
7x=26
x=26/7

h)5x-15-4x-8=2+3-6x
x-23=5-6x
x+6x=5+23
7x=28
x=4
