Question

your answer must be simplified.
15 < -5x

Explanation:

Step1: Divide both sides by -5

When dividing an inequality by a negative number, the inequality sign flips. So, divide both sides of \(15 < -5x\) by \(-5\):
\(\frac{15}{-5} > \frac{-5x}{-5}\)

Step2: Simplify both sides

Simplify the left - hand side: \(\frac{15}{-5}=-3\)
Simplify the right - hand side: \(\frac{-5x}{-5}=x\)
So we get \(-3 > x\) or \(x < - 3\)

Answer:

\(x < - 3\)
