11x-2=-3-2x
Subtract 8 from 5 to get -3.
11x-2+2x=-3
Add 2x to both sides.
13x-2=-3
Combine 11x and 2x to get 13x.
13x=-3+2
Add 2 to both sides.
13x=-1
Add -3 and 2 to get -1.
x=\frac{-1}{13}
Divide both sides by 13.
x=-\frac{1}{13}
Fraction \frac{-1}{13} can be rewritten as -\frac{1}{13} by extracting the negative sign.
