Question

A washer and a dryer cost $687 combined. The washer costs $63 less than the dryer. What is the cost of the dryer?

Answer 1

375

Explanation:

You can set up an equation here.

Let the washer's cost be x and the cost of the dryer to be y.

You can set up the following equations:

`x+y=687\\x=y-63`

After getting those two equations you can substitute the second into the first equation to get this:

`y-63+y=687`

Simplifying that gives:

`2y-63=687\\2y=750\\y=375`
