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