-x+10=2y
Swap sides so that all variable terms are on the left hand side.
-x=2y-10
Subtract 10 from both sides.
\frac{-x}{-1}=\frac{2y-10}{-1}
Divide both sides by -1.
x=\frac{2y-10}{-1}
Dividing by -1 undoes the multiplication by -1.
x=10-2y
Divide -10+2y by -1.
2y=10-x
The equation is in standard form.
\frac{2y}{2}=\frac{10-x}{2}
Divide both sides by 2.
y=\frac{10-x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{x}{2}+5
Divide -x+10 by 2.
