12x-21=4x-25
Use the distributive property to multiply 3 by 4x-7.
12x-21-4x=-25
Subtract 4x from both sides.
8x-21=-25
Combine 12x and -4x to get 8x.
8x=-25+21
Add 21 to both sides.
8x=-4
Add -25 and 21 to get -4.
x=\frac{-4}{8}
Divide both sides by 8.
x=-\frac{1}{2}
Reduce the fraction \frac{-4}{8} to lowest terms by extracting and canceling out 4.
