12-3x=6+12x
Use the distributive property to multiply 6 by 1+2x.
12-3x-12x=6
Subtract 12x from both sides.
12-15x=6
Combine -3x and -12x to get -15x.
-15x=6-12
Subtract 12 from both sides.
-15x=-6
Subtract 12 from 6 to get -6.
x=\frac{-6}{-15}
Divide both sides by -15.
x=\frac{2}{5}
Reduce the fraction \frac{-6}{-15} to lowest terms by extracting and canceling out -3.
