Solve the inequality and describe the solution set.
y
–
6
≥
12
y
–
6
≥
12
First, we add 6 to both sides of the inequalities to isolate the variable y:
y - 6 + 6 ≥ 12 + 6
y ≥ 18
The solution set is all real numbers greater than or equal to 18. We can represent this solution set using interval notation as [18, ∞).
