Question

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

Answer 1

Answer:

$x\geq -3$

Step-by-step 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.
