-6=4U
Variable U cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by U.
4U=-6
Swap sides so that all variable terms are on the left hand side.
U=\frac{-6}{4}
Divide both sides by 4.
U=-\frac{3}{2}
Reduce the fraction \frac{-6}{4} to lowest terms by extracting and canceling out 2.
