Answer:
A
Explanation:
Lets treat this linear inequality as a linear equation first and simplify it and "solve" for x.
-3x+12 ≤ 15
Subtract 12 on both sides
-3x≤3
Now divide -3 on both sides. However, don't fall into the trap many fall into. When dividing or multiplying an inequality by a negative number, you must switch the sign direction.
x≥-1
