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