3u=8-4y
Subtract 4y from both sides.
\frac{3u}{3}=\frac{8-4y}{3}
Divide both sides by 3.
u=\frac{8-4y}{3}
Dividing by 3 undoes the multiplication by 3.
4y=8-3u
Subtract 3u from both sides.
\frac{4y}{4}=\frac{8-3u}{4}
Divide both sides by 4.
y=\frac{8-3u}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{3u}{4}+2
Divide 8-3u by 4.
