Step-by-step explanation:
-1/3 a + 4 ≤ 0
3*(-1/3a) + 4*3 ≤ 0*3
-a + 12 ≤ 0
12 ≤ a
12 ⩾a
a⩾12
Answer:
Option 1 - X = 9
Step-by-step explanation:
The solution to this equation, x - 15 = - 6
Solving the following,
Step 1: x - 15 = -6
Replace all the numerical values in one side and x digits on the other side
