4x+7y=28
solve for y
explain how , i saw in previously asked questions like this one that the answer was 4-4/7x. i typed this answer into mymathlab and was told it was wrong. what is the answer?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
