2x=5-2y
Subtract 2y from both sides.
\frac{2x}{2}=\frac{5-2y}{2}
Divide both sides by 2.
x=\frac{5-2y}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{5}{2}-y
Divide 5-2y by 2.
2y=5-2x
Subtract 2x from both sides.
\frac{2y}{2}=\frac{5-2x}{2}
Divide both sides by 2.
y=\frac{5-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{5}{2}-x
Divide 5-2x by 2.
