Answer 1

3x+23=2x+59
3x-2x=59-23
x=36

3(36)+23=2(36)+59
108+23=72+59
131=131
-----------------------------
x+12=17
x=17-12
x=5

5+12=17
17=17
-----------------------------
2x-4=x+9
2x-x=9+4
x=13

2(13)-4=13+9
26-4=22
22=22
-----------------------------
5x-10=4x-12
5x-4x=-12+10
x=-2

5(-2)-10=4(-2)-12
-10-10= -8-12
-20=-20
