Question

-18 - 4y > 20
Can some1 solve this pls?

Answer 1

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

Answer 2

y < -19/2

Explanation:

-18 - 4y > 20

Add 18 to each side

-18+18 - 4y > 20+18

-4y > 38

Divide each side by -4, remembering to flip the inequality

-4y/-4 < 38/-4

y < -19/2
