Answer:
x ≥ 18
Step-by-step explanation:
This can be simplified by changing the sign on the 12 value. This is because you are subtracting a negative number and two negatives make a positive (- - = +):
x (--12) ≥ 30
x + 12 ≥ 30
Subtract 12 from both sides:
x + 12 - 12 ≥ 30 - 12
x ≥ 18
Hope this helps!
