Solve the inequality 4-y > 5 for y. Show and justify your steps.

y < - 1

Step-by-step explanation:

Given

4 - y > 5 (subtract 4 from both sides)

- y > 1

Multiply both sides by - 1, reversing the inequality symbol as a consequence of multiplying by a negative quantity, that is

y < - 1 ← inequality symbol reversed
