-\frac{5}{2}\times 8\geq v
Multiply both sides by 8. Since 8 is positive, the inequality direction remains the same.
\frac{-5\times 8}{2}\geq v
Express -\frac{5}{2}\times 8 as a single fraction.
\frac{-40}{2}\geq v
Multiply -5 and 8 to get -40.
-20\geq v
Divide -40 by 2 to get -20.
v\leq -20
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
