-5x-8x-4=3x
Use the distributive property to multiply -2 by 4x+2.
-13x-4=3x
Combine -5x and -8x to get -13x.
-13x-4-3x=0
Subtract 3x from both sides.
-16x-4=0
Combine -13x and -3x to get -16x.
-16x=4
Add 4 to both sides. Anything plus zero gives itself.
x=\frac{4}{-16}
Divide both sides by -16.
x=-\frac{1}{4}
Reduce the fraction \frac{4}{-16} to lowest terms by extracting and canceling out 4.
