Answer: x ≥ 7
Explanation:
Problem: 8 ≤ x - 15
1. Move the variable to the left-hand side and change its signs
-8 - x ≤ - 15
2. Move the constant to the right-hand side and change its signs
-x ≤ -15 + 8
3. Calculate the sum
- x ≤ -7
4. Change the signs on both sides of the inequality and flip the inequality sign
x ≥ 7
