Question

A washer and a dryer cost $797 combined. The washer costs $53 less than the dryer. What is the cost of the dryer?

Answer 1

w + d = 797

w = d - 53

Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.

d - 53 + d = 797

2d = 850

d = 425

I bet you can get the washer!
