what value of x is in the solution set of the inequality -5x - 15 > 10 + 20x? -2 -1 0 1
what value of x is in the solution set of the inequality -5x - 15 > 10 + 20x? -2 -1 0 1
Answer
Explanation:
Step1: Move like - terms together
Add (5x) to both sides and subtract 10 from both sides of the inequality (-5x - 15>10 + 20x). We get (-15-10>20x + 5x).
Step2: Simplify both sides
(-25>25x).
Step3: Solve for (x)
Divide both sides of the inequality by 25. When dividing an inequality by a positive number, the direction of the inequality sign remains the same. So (x<-1).
