-2=8u
Variable u cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by u.
8u=-2
Swap sides so that all variable terms are on the left hand side.
u=\frac{-2}{8}
Divide both sides by 8.
u=-\frac{1}{4}
Reduce the fraction \frac{-2}{8} to lowest terms by extracting and canceling out 2.
