-8y-x-3x=4
Subtract 3x from both sides.
-8y-4x=4
Combine -x and -3x to get -4x.
-4x=4+8y
Add 8y to both sides.
-4x=8y+4
The equation is in standard form.
\frac{-4x}{-4}=\frac{8y+4}{-4}
Divide both sides by -4.
x=\frac{8y+4}{-4}
Dividing by -4 undoes the multiplication by -4.
x=-2y-1
Divide 4+8y by -4.
-8y=3x+4+x
Add x to both sides.
-8y=4x+4
Combine 3x and x to get 4x.
\frac{-8y}{-8}=\frac{4x+4}{-8}
Divide both sides by -8.
y=\frac{4x+4}{-8}
Dividing by -8 undoes the multiplication by -8.
y=\frac{-x-1}{2}
Divide 4+4x by -8.
