Question

Given: 15x < -45.

Choose the solution set.

x < -3
x
x
x

Answer 1

Divide both sides by 15 to isolate x

15x < -45
15x/15 < -45/15
x < -3

So the answer is choice A

Answer 2

x < -3

Explanation:

Given inequality,

`15x<-45`

Divide both sides by 15 ( division property of inequality ),

We get,

`x<-3`

That is, the possible values of x are the numbers less than -3,

Thus, in builder form, the solution of the given inequality is,

x

First option is correct.
