Answer 1

•
-3x+7-2x-1=8x-9+11x-6
-3x-2x+7-1=8x+11x-9-6
-5x+6=19x-15
6+15=19x+5x
21=24x
21/24=x

•
5x-10+3x-1=10-6x+7x+1
5x+3x-10-1=-6x+7x+10+1
8x-11=x+11
8x-x=11+11
7x=22
x=22/7

•
-9x+10=x-20
10+20=x+9x
30=10x
30/10=x
3=x

Answer 2

-3x+7-2x-1=8x-9+11x-6
-3x-2x-8x-11x= -9-6-7+1
-24x=-21
X=-21/-24
X=7/8

5x-10+3x-1=10-6x+7x+1
5x+3x+6x-7x= 10+1+10+1
7x=22
X=22/7

-9x+10=x-20
-9x-x=-20-10
-10x=-30
X=-30/-10
X= 3
