A washer and dryer cost $869 combined. The washer cost $81 less than the dryer. What is the cost of the dryer?
marysya [2.9K]
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475

let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)
