8x-6x+12=3x\times 6
Use the distributive property to multiply -3 by 2x-4.
2x+12=3x\times 6
Combine 8x and -6x to get 2x.
2x+12=18x
Multiply 3 and 6 to get 18.
2x+12-18x=0
Subtract 18x from both sides.
-16x+12=0
Combine 2x and -18x to get -16x.
-16x=-12
Subtract 12 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-12}{-16}
Divide both sides by -16.
x=\frac{3}{4}
Reduce the fraction \frac{-12}{-16} to lowest terms by extracting and canceling out -4.
