Question

Washer and dryer cost $784 combined. The washer cost $66 less than the dryer. What is the cost of the dryer.

Answer 1

$425

Explanation:

Let the dryer cost x

and the dish washer cost y

x+y=784-----------1

y=x-66-------------2

put the value of y=x-66 in 1

x+x-66=784

2x= 784+66

2x=850

x=850/2

x=425

Hence the dryer cost $425
