Solve each inequality using the Addition Property of Inequality.

Law Incorporation [45]

Answer:

y ≥ 28

Step-by-step explanation:

Isolate the variable. Treat the inequality sign as a equal sign, what you do to one side, you do to the other. Add 6 to both sides:

y - 6 (+6) ≥ 22 (+6)

y ≥ 22 + 6

y ≥ 28

y ≥ 28 is your answer.
