Solve the Inequality for r -r/3<=6

$- \frac{r}{3} \leq 6$

Divide each term in $- \frac{r}{3} \leq 6$ by $- 1$ and simplify.

Divide each term in $- \frac{r}{3} \leq 6$ by $- 1$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- \frac{r}{3}}{- 1} \geq \frac{6}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{\frac{r}{3}}{1} \geq \frac{6}{- 1}$

Divide $\frac{r}{3}$ by $1$ .

$\frac{r}{3} \geq \frac{6}{- 1}$

Simplify the right side.
