4x+27+53=6x-51+6x-51
Combine 3x and x to get 4x.
4x+80=6x-51+6x-51
Add 27 and 53 to get 80.
4x+80=12x-51-51
Combine 6x and 6x to get 12x.
4x+80=12x-102
Subtract 51 from -51 to get -102.
4x+80-12x=-102
Subtract 12x from both sides.
-8x+80=-102
Combine 4x and -12x to get -8x.
-8x=-102-80
Subtract 80 from both sides.
-8x=-182
Subtract 80 from -102 to get -182.
x=\frac{-182}{-8}
Divide both sides by -8.
x=\frac{91}{4}
Reduce the fraction \frac{-182}{-8} to lowest terms by extracting and canceling out -2.
