Answer: y = 3

Explanation:

1. Distribute the 4 to the terms in the parenthesis.

20 = 4y + 32 - 8y

2. Combine like terms (those containing y).

20 = -4y + 32

3. Isolate terms with y by subtracting 32 from both sides.

-12 = -4y

4. Divide both sides by -4.

3 = y

Answer:

y = 3

Explanation:

20 = 4 (y + 8) - 8y

20 = 4y + 32 - 8y

20 - 32 = 4y - 8y

-12 = -4y

-4y = -12

-4y/-4 = -12/-4

y = 3

To check

20 = 4 (y + 8) - 8y

20 = 4 (3 + 8) - 8(3)

20 = 12 + 32 - 24

20 = 44 - 24

20 = 20

Correct~
