Question

3x + 5 < 2x - 8 is:

all values more than -13.
all values less than -13. all values less than 3. all values less than -3.

Answer 1

all values less than -13

Explanation:

3x + 5 < 2x - 8

3x + 5 - 5 = 2x - 8 - 5 ==> isolate x by subtracting 5 on both sides

3x < 2x - 13 ==> simplify

3x - 2x < 2x - 2x - 13 ==> subtract 2x from both sides to move x to the left

side of the inequality

x < -13 ==> simplify

Hence, the answer is all values less than -13.
