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