Question

Can pls someone help me? and show how it did it?

Answer 1

`x\geq -3`

Explanation:

We can start by combining like terms:

`(3x-7x)+(-5+2)\leq 9\\-4x-3\leq 9`

We want to isolate x, so we must add 3 and divide by -4:

`(-4x-3\leq 9)+3\\(-4x\leq 12)/-4\\\\x\geq -3`

Because we had to divide by -4, the inequality sign had to flip.
