Answer: y = -2x - 14
Step-by-step explanation:
First, distribute the "-2" to every term inside of the parenthesis to get
"-4x - 2y = 28", then isolate the term with "y" by adding "4x" to each side (to remove the "-4x") to get "-2y = 4x + 28", then divide both sides by "-2" to isolate the "y" (make sure you distribute this to all terms on the right side) to get "y = -2x - 14", which is your final answer.
-2(2x + y) = 28
-4x - 2y = 28
-2y = 28 + 4x
y = -2x - 14
