an inequality is shown. solve the inequality and graph the solution on the number line. 5x + 15 ≤ 2x - 30

an inequality is shown. solve the inequality and graph the solution on the number line. 5x + 15 ≤ 2x - 30
Answer
Explanation:
Step1: Subtract 2x from both sides
$5x - 2x+15\leq2x - 2x - 30$ $3x + 15\leq - 30$
Step2: Subtract 15 from both sides
$3x+15 - 15\leq - 30 - 15$ $3x\leq - 45$
Step3: Divide both sides by 3
$\frac{3x}{3}\leq\frac{- 45}{3}$ $x\leq - 15$
To graph on the number - line, draw a closed circle at - 15 (because the inequality is $\leq$) and shade to the left.
Answer:
$x\leq - 15$; On the number - line, a closed circle at - 15 and shade to the left.
