Answer:
x ≥ -3
Explanation:
To determine the solution to the inequality, we need to isolate the variable and its coefficient on one side of the equation. Furthermore, isolate the variable by dividing the coefficient by both sides of the equation. The inequality obtained after doing these steps is the solution to the inequality.
Given inequality:
As said above, let's isolate "x" and it's coefficient on one side of the equation. This can be done by subtracting "x + 15" to both sides of the equation.
- ⇒ 4x + 15 - (x + 15) ≥ x + 6 - (x + 15)
- ⇒ 4x + 15 - x - 15 ≥ x + 6 - x - 15
- ⇒ 3x ≥ -9
As said above, let's further isolate "x" by dividing the coefficient of "x" to both sides of the equation.
Therefore, the solution is x ≥ -3.
