Solve for x
x = -\frac{7}{2} = -3\frac{1}{2} = -3.5
Solve for y
y = \frac{7}{2} = 3\frac{1}{2} = 3.5

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