Answer:
A. 3
Step-by-step explanation:
3x > 12 OR x + 1 ≤ -2
÷3 ÷3 OR - 1 -1
x > 4 x ≤ -3
This means that any number greater than four is a value for the solution. And any number equal to or less than -3 is part of the value for the solution.
D. -3 cannot be it because it is part of x ≤ -3
C. -5 cannot be it because it is part of x ≤ -5
B. 7 cannot be it because it is part of x > 4
A. 3 is true because it is not a part of either equation. So the answer is A.
I hope that this helps! :)
