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
Subtract 21 from both sides.
8x=4
Subtract 21 from 25 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.
