Question

A washer and a dryer cost $714 combined. The washer costs $64 more than the dryer. What is the cost of the dryer?

Answer 1

293 because 714/2 is 357 - 64 = 293

Answer 2

let washer be w
let dryer be d

w + d = 714
w = d + 64

(d + 64) + d = 714

2d + 64 = 714
2d + 64 (-64) = 714 (-64)
2d = 650
2d/2 = 650/2
d = 325

The dryer is 325 dollars

hope this helps
