3=4e-3f
Multiply both sides by 3.
4e-3f=3
Swap sides so that all variable terms are on the left hand side.
-3f=3-4e
Subtract 4e from both sides.
\frac{-3f}{-3}=\frac{3-4e}{-3}
Divide both sides by -3.
f=\frac{3-4e}{-3}
Dividing by -3 undoes the multiplication by -3.
f=\frac{4e}{3}-1
Divide 3-4e by -3.
