Answer:
x = -3/2
Step-by-step explanation:
1) Expand.
[tex]3x+2x-2=9x+4[/tex]
2) Simplify 3x+2x-2 to 5x-2.
[tex]5x-2=9x+4[/tex]
3) Subtract 5x from both sides.
[tex]-2=9x+4-5x[/tex]
4) Simplify [tex]9x+4-5x[/tex] to [tex]4x+4[/tex].
[tex]-2=4x+4[/tex]
5) Subtract 4 from both sides.
[tex]-2-4=4x[/tex]
6) Simplify - 2 - 4 to -6.
[tex]-6=4x[/tex]
7) Divide both sides by 4.
-6/4 = x
8) Simplify 6/4 to 3/2.
-3/2 = x
9) Switch sides.
x = -3/2
