8x-y=-11
Multiply 2 and 4 to get 8.
8x=-11+y
Add y to both sides.
8x=y-11
The equation is in standard form.
\frac{8x}{8}=\frac{y-11}{8}
Divide both sides by 8.
x=\frac{y-11}{8}
Dividing by 8 undoes the multiplication by 8.
8x-y=-11
Multiply 2 and 4 to get 8.
-y=-11-8x
Subtract 8x from both sides.
-y=-8x-11
The equation is in standard form.
\frac{-y}{-1}=\frac{-8x-11}{-1}
Divide both sides by -1.
y=\frac{-8x-11}{-1}
Dividing by -1 undoes the multiplication by -1.
y=8x+11
Divide -11-8x by -1.
