3u=4+5v
Add 5v to both sides.
3u=5v+4
The equation is in standard form.
\frac{3u}{3}=\frac{5v+4}{3}
Divide both sides by 3.
u=\frac{5v+4}{3}
Dividing by 3 undoes the multiplication by 3.
-5v=4-3u
Subtract 3u from both sides.
\frac{-5v}{-5}=\frac{4-3u}{-5}
Divide both sides by -5.
v=\frac{4-3u}{-5}
Dividing by -5 undoes the multiplication by -5.
v=\frac{3u-4}{5}
Divide 4-3u by -5.
