4x+8=4y
Swap sides so that all variable terms are on the left hand side.
4x=4y-8
Subtract 8 from both sides.
\frac{4x}{4}=\frac{4y-8}{4}
Divide both sides by 4.
x=\frac{4y-8}{4}
Dividing by 4 undoes the multiplication by 4.
x=y-2
Divide -8+4y by 4.
4y=4x+8
The equation is in standard form.
\frac{4y}{4}=\frac{4x+8}{4}
Divide both sides by 4.
y=\frac{4x+8}{4}
Dividing by 4 undoes the multiplication by 4.
y=x+2
Divide 8+4x by 4.
