Question

Given 3x <9 Choose the solution set

Answer 1

Divide both sides by 3.
x < 3

The solution is x < 3

Answer 2

`x<3` or
`(-\infty,3)`

Explanation:

We have been given an inequality
`3x<9`. We are asked to find the solution set for our given inequality.

We will divide both sides of our inequality by 3 to solve for x.

`(3x)/(3)<(9)/(3)`

`x<3`

Therefore, the solution for our given inequality will be all values of x less than 3, that is
`(-\infty,3)` in interval notation.
