Question

What is the solution to 9x−6<21?

Select one:

x<4

x<3

x<2

x<5

Answer 1

`x > 3`

Explanation:

1) Add 6 to both sides.

`9x > 21 + 6`

2) Simplify 21 + 6 to 27.

`9x > 27`

3) Divide both sides by 9.

`x > (27)/(9)`

4) Simplify 27/9 to 3.

`x > 3`

Therefor, the answer is option B. x > 3.
