-2x+17=-y
Subtract y from both sides. Anything subtracted from zero gives its negation.
-2x=-y-17
Subtract 17 from both sides.
\frac{-2x}{-2}=\frac{-y-17}{-2}
Divide both sides by -2.
x=\frac{-y-17}{-2}
Dividing by -2 undoes the multiplication by -2.
x=\frac{y+17}{2}
Divide -y-17 by -2.
y+17=2x
Add 2x to both sides. Anything plus zero gives itself.
y=2x-17
Subtract 17 from both sides.
