Question

Algebra 1 help please

Answer 1

X = 4

Explanation:

First, You need to rewrite the expression to look like this

9 - 3x = 12

An inequality basically means equals and the next step is to subtract 9 from both sides so it would look like this

3x = 12

Then divide both sides by 3 to get

x = 4

Answer 2

3x-9≤12

3x≤21

x≤7

-5x+10≤20

-5x≤10

x≥-2
