Answer:
y < -9.5
Explanation:
-18 - 4y > 20
Add 18 to both sides of the inequality.
-18 + 18 - 4y > 20 + 18
Add -18 + 18 which gets you 0.
0 - 4y > 20 + 18
Subtract 0 - 4y which gets you -4y.
-4y > 20 + 18
Add 20 + 18 to get 38.
-4y > 38
Divide both sides by -4 and change the inequality direction.
y < 38/-4
Cancel out 2 as a common factor from 38/-4.
y < 19/-2
Divide 19 / -2 which gets you -9.5.
-9.5
