Write inequality: Write down the inequality to start solving it. $\newline$ $(\frac{3}{2})q \leq (\frac{9}{2})q - 18$
Isolate q terms: To isolate q, we need to get all the q terms on one side. Subtract $(\frac{3}{2})q$ from both sides of the inequality. $\newline$ $(\frac{3}{2})q - (\frac{3}{2})q \leq (\frac{9}{2})q - (\frac{3}{2})q - 18$ $\newline$ This simplifies to: $\newline$ $0 \leq (\frac{6}{2})q - 18$
Simplify right side: Simplify the right side of the inequality by combining like terms. $0 \leq 3q - 18$
Add $18$ to both sides: Add $18$ to both sides of the inequality to isolate the term with $q$ . $\newline$ $0 + 18 \leq 3q - 18 + 18$ $\newline$ This simplifies to: $\newline$ $18 \leq 3q$
Divide by $3$ : Divide both sides of the inequality by $3$ to solve for $q$ . $\frac{18}{3} \leq \frac{3q}{3}$ This simplifies to: $6 \leq q$
Rewrite inequality: Rewrite the inequality in a more conventional way. $q \geq 6$
