-8x=8+8y
Add 8y to both sides.
-8x=8y+8
The equation is in standard form.
\frac{-8x}{-8}=\frac{8y+8}{-8}
Divide both sides by -8.
x=\frac{8y+8}{-8}
Dividing by -8 undoes the multiplication by -8.
x=-\left(y+1\right)
Divide 8+8y by -8.
-8y=8+8x
Add 8x to both sides.
-8y=8x+8
The equation is in standard form.
\frac{-8y}{-8}=\frac{8x+8}{-8}
Divide both sides by -8.
y=\frac{8x+8}{-8}
Dividing by -8 undoes the multiplication by -8.
y=-\left(x+1\right)
Divide 8+8x by -8.
