$325

Explanation:

Let's say that the cost of the dryer is d.

This means that:

d+(d+37)=687

Where (d+37) is the cost of the washer

Simplify it:

2d+37=687

And solve it:

2d=687-37

2d=650

d=650/2

d=325

The washer costs $362 and the dryer costs $325 dolars.

Explanation:

There is probably an easier way to do this, but here's how I did it:
First I took $37 off the total cost, because we know that the washer costs $37 more then the dryer.
Then I devided the answer by two and added the $37 to the cost for the washer.

The sum:
687 - 37 = 650
650 / 2 = 325 (price of dryer)
325 + 37 = 362 (price of washer)
