How do I solve one step inequality’s

Answer 1

`x < -20`

Explanation:

Given the following question:


`x+8 < -12`

In order to solve one step inequalities, we solve how we would normally solve a one-step equation and then graph the answer on a number line.


`x+8 < -12`

`8-8=0`

`-12-8=-20`

`x < -20`

Now to graph the inequality on a number line, keep a few things in mind:
. x is less than -20 which means the line would go the opposite way of the negative 20.
. < is a greater than sign, not a greater than or equal sign (≤) so the number line will have a open point.
. The number line will have a point on -20.

Hope this helps.
