-10x+10=-y
Subtract y from both sides. Anything subtracted from zero gives its negation.
-10x=-y-10
Subtract 10 from both sides.
\frac{-10x}{-10}=\frac{-y-10}{-10}
Divide both sides by -10.
x=\frac{-y-10}{-10}
Dividing by -10 undoes the multiplication by -10.
x=\frac{y}{10}+1
Divide -y-10 by -10.
y+10=10x
Add 10x to both sides. Anything plus zero gives itself.
y=10x-10
Subtract 10 from both sides.
