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