What value of x is in the solution set of -5x - 15 > 10 + 20x?
-2, -1, 0, 1

Solution:

Given: - 5x - 15 > 10 + 20x

Let us solve the inequality by isolating the variable x.

Add 5x on both sides

- 5x - 15 + 5x > 10 + 20x + 5x

- 15 > 10 + 25x

Subtract 10 from both sides

- 15 - 10 > 10 - 10 + 25x

- 25 > 25x

Divide both sides by - 25

-1 > x

x < - 1

From the values in the given solution set, we have -2 which is the required value.

What value of x is in the solution set of -5x - 15 > 10 + 20x?
-2, -1, 0, 1

Summary:

The value of x in the solution set of - 5x - 15 > 10 + 20x is x < - 1 and the required value from the solution set is -2.
