Unfortunately I could not answer the question on the same day you asked, but I'll help anyway in case you haven't completed it yet. Patience is a virtue, after all!
Answer:
X is less than or equal to -3
Explanation:
(<= means "is less than or equal to")
If we do reverse math, we can subtract 1 from both sides, leaving us with 4x <=-12. After that, we can divide both sides by 4, leaving us with X<=-3. This also falls within the parameters of 3x<=0, so no further solving is required.
Hope this helps!
