-\frac{3}{4}\times 8\leq u
Multiply both sides by 8. Since 8 is positive, the inequality direction remains the same.
\frac{-3\times 8}{4}\leq u
Express -\frac{3}{4}\times 8 as a single fraction.
\frac{-24}{4}\leq u
Multiply -3 and 8 to get -24.
-6\leq u
Divide -24 by 4 to get -6.
u\geq -6
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
