-6=-9u
Variable u cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by u.
-9u=-6
Swap sides so that all variable terms are on the left hand side.
u=\frac{-6}{-9}
Divide both sides by -9.
u=\frac{2}{3}
Reduce the fraction \frac{-6}{-9} to lowest terms by extracting and canceling out -3.
