2x+4=-8-6x
Combine 13x and -11x to get 2x.
2x+4+6x=-8
Add 6x to both sides.
8x+4=-8
Combine 2x and 6x to get 8x.
8x=-8-4
Subtract 4 from both sides.
8x=-12
Subtract 4 from -8 to get -12.
x=\frac{-12}{8}
Divide both sides by 8.
x=-\frac{3}{2}
Reduce the fraction \frac{-12}{8} to lowest terms by extracting and canceling out 4.
