Question

solve for q.
$\frac{q}{-1}+20geq13$

Explanation:

Step1: Subtract 20 from both sides

$\frac{q}{-1}+20 - 20\geq13 - 20$
$\frac{q}{-1}\geq - 7$

Step2: Multiply both sides by -1 and reverse the inequality sign

When multiplying an inequality by a negative number, the direction of the inequality sign changes. So $q\leq(-7)\times(-1)$
$q\leq7$

Answer:

$q\leq7$
