Question 1001094
Mrs. Atkins pays 1800 for a new refrigerator, washer, and dryer. The refrigerator costs 250 more than the washer. The dryer costs half as much as the washer. How much does does the washer cost? 
-----
Equations:
r + w + d = 1800
r = w+250
d = (w/2)
-------
Substitute for "r" and for "d", and solve for "w"::
(w+25) + w + (w/2) = 1800
2.5w + 25 = 1800
2.5w = 1775
w = $710 (cost of the washer)
