Answer:

375

Step-by-step 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:

[tex]x+y=687\\x=y-63[/tex]

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

[tex]y-63+y=687[/tex]

Simplifying that gives:

[tex]2y-63=687\\2y=750\\y=375[/tex]
