You need to isolate the "x" in both inequalities

5x + 7 ≤ -3     Subtract 7 on both sides

5x ≤ -10    Divide 5 on both sides

x ≤ -2


3x - 4 ≥ 11     Add 4 on both sides

3x ≥ 15  Divide 3 on both sides

x ≥ 5


This is your simplified inequalities:

5x + 7 ≤ -3 or 3x - 4 ≥ 11   --------->     x ≤ -2 or x ≥ 5      Your answer is A
