Answer
$0\gt r$
Work Step by Step
$-\frac{3}{4}\gt r-\frac{3}{4}$ : add $\frac{3}{4}$ to both sides
$-\frac{3}{4}+\frac{3}{4} \gt r-\frac{3}{4}+\frac{3}{4}$ : simplify
$0\gt r$
Verify that 0 is not a solution.
$-\frac{3}{4}\overset?\gt 0-\frac{3}{4}$
$-\frac{3}{4}\ /\!\!\!\!\!\gt-\frac{3}{4}\checkmark$
Verify that a number less than 0 is a solution.
$-\frac{3}{4}\overset?\gt -1-\frac{3}{4}$
$-\frac{3}{4} \gt -1\frac{3}{4}\checkmark$
