7-5x=1-x
Subtract 1 from 8 to get 7.
7-5x+x=1
Add x to both sides.
7-4x=1
Combine -5x and x to get -4x.
-4x=1-7
Subtract 7 from both sides.
-4x=-6
Subtract 7 from 1 to get -6.
x=\frac{-6}{-4}
Divide both sides by -4.
x=\frac{3}{2}
Reduce the fraction \frac{-6}{-4} to lowest terms by extracting and canceling out -2.
