2 - 4 ( y + 4 ) = 2y + 16 solve for y

Answers

Answer 1

Answer:

Answer:

y = -5

Step-by-step explanation:

To solve for a variable, take the following steps:

Distribute by multiplying into each term in the parenthesis
Combine like terms
Move terms across the equal sign using inverse operations

2 - 4 (y + 4) = 2y + 16 Distribute

2 - 4y - 16 = 2y + 16 Combine 2-16

-14 - 4y = 2y + 16 Add 4y to both sides

-14 = 6y + 16 Subtract 16 to both sides

-30 = 6y Divide by 6

y = -5
