-4+3x=13x+11-5x
Subtract 9 from 5 to get -4.
-4+3x=8x+11
Combine 13x and -5x to get 8x.
-4+3x-8x=11
Subtract 8x from both sides.
-4-5x=11
Combine 3x and -8x to get -5x.
-5x=11+4
Add 4 to both sides.
-5x=15
Add 11 and 4 to get 15.
x=\frac{15}{-5}
Divide both sides by -5.
x=-3
Divide 15 by -5 to get -3.
