Isolate the variable on one side of the inequality to find the solution. $\frac{r}{3}\geq-4\longrightarrow$ multiply each side by 3 $\frac{r}{3}\times3\geq-4\times3\longrightarrow$ multiply $r\geq-12$ -12 is the solution at the endpoint. Any other number that is greater than -12 is also part of the solution set.
