Question
solve for x. your answer must be simplified. -30 < \frac{x}{-4}
Step1: Multiply both sides by -4
When multiplying an inequality by a negative number, the inequality sign flips. So we have \(-30\times(-4) > x\) (note the flip from < to >).
Step2: Calculate -30×(-4)
\(-30\times(-4) = 120\), so the inequality becomes \(120 > x\) or \(x < 120\).
