A washer and a dryer cost $1029 combined. The washer costs $79 more than the dryer. What is the cost of the dryer?

Darina [25.2K]

X = dryer
(X+79) = washer
X + (X+79) = $1029
Therefore, x+x+79= 1029 or 2x+79=1029
Solve for x

2x = 1029-79
2x = 950

2x/2 = 950/2

X= $475 The price of the dryer is $475
