In the given problem, apply your knowledge in algebraic expression specially in solving unknown variables of linear equation system.
What are the possible values of y if x = 4 in the inequality x - 2y ≤ 5?
→ x = 4, x - 2y ≤ 5
4 - 2y ≤ 5
4 - 2y ≤ 5
-2y ≤ 5 - 4
-2y ≤ 1
y ≤ -½
The posible values for y are -1/2, -1, -3/2, -2 and so on. It can be written in the form of y ≤ -1/2 or y = [-1/2, -1, -3/2, -2, -5/2, -3, ...]
