Q. Solve for

r

.

9 + -1r \leq 7

Isolate variable term: Isolate the variable term $-1r$ in the inequality $9 + -1r \leq 7$ . $\newline$ $9 + -1r - 9 \leq 7 - 9$ $\newline$ $-1r \leq -2$
Divide by $-1$ : Divide both sides of the inequality by $-1$ to solve for $r$ . Remember that dividing by a negative number reverses the inequality sign. $\frac{-1r}{-1} \geq \frac{-2}{-1}$ $r \geq 2$
