A washer and a dryer cost $560 combined. The washer costs $90 less than the dryer.
What is the cost of the dryer?
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let X be the cost of the dryer, in dollars.
Then the cost of the washer is (X-90) dollars.
Together they cost $560
X + (X-90) = 560
2X = 560 + 90
2X = 650
X = 650/2 = 325.
ANSWER. The dryer costs $325.
