-x=7-2y
Subtract 2y from both sides.
\frac{-x}{-1}=\frac{7-2y}{-1}
Divide both sides by -1.
x=\frac{7-2y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=2y-7
Divide 7-2y by -1.
2y=7+x
Add x to both sides.
2y=x+7
The equation is in standard form.
\frac{2y}{2}=\frac{x+7}{2}
Divide both sides by 2.
y=\frac{x+7}{2}
Dividing by 2 undoes the multiplication by 2.
