8x+16=4y
Swap sides so that all variable terms are on the left hand side.
8x=4y-16
Subtract 16 from both sides.
\frac{8x}{8}=\frac{4y-16}{8}
Divide both sides by 8.
x=\frac{4y-16}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{y}{2}-2
Divide -16+4y by 8.
4y=8x+16
The equation is in standard form.
\frac{4y}{4}=\frac{8x+16}{4}
Divide both sides by 4.
y=\frac{8x+16}{4}
Dividing by 4 undoes the multiplication by 4.
y=2x+4
Divide 16+8x by 4.
