Consider the inequality –5(x + 7) < –10. write an inequality representing the solution for x.

x < -5

Explanation:

We just have to isolate x to be able to answer the question.

We start with

–5(x + 7) < –10

-5x - 35 < -10

-5x < 25

x < -5

So, x < -5 is your answer.

We could also have done it this other way:

–5(x + 7) < –10

x + 7 < 2

x < -5

the answer is x < - 5
