3x-12=12x
Use the distributive property to multiply 3 by x-4.
3x-12-12x=0
Subtract 12x from both sides.
-9x-12=0
Combine 3x and -12x to get -9x.
-9x=12
Add 12 to both sides. Anything plus zero gives itself.
x=\frac{12}{-9}
Divide both sides by -9.
x=-\frac{4}{3}
Reduce the fraction \frac{12}{-9} to lowest terms by extracting and canceling out 3.
