Answer:
x = The set of real numbers greater than or equal to -7
Explanation:
Given:
4x - 12 ≤ 16 + 8x
Here we need to solve for x.
Isolate the variables and constant terms
Subtract 4x on both sides, we get
4x - 4x - 12 ≤ 16 + 8x - 4x
-12≤ 16 + 4x
Now subtract 16 on both sides, we get
-12 - 16 ≤ 16 -16 + 4x
-28 ≤ 4x
This can be written as
4x ≥ -28
Divide both sides by 4, we get
x ≥ -28/4
x ≥ - 7
x = The set of real numbers greater than or equal to -7
