Accepted Solution
A:
-------------------------------------------------------------- Define x : -------------------------------------------------------------- Let the dryer be x. Dryer = x Washer = x -53
-------------------------------------------------------------- Construct Equation : -------------------------------------------------------------- The washer and the dryer cost $847 ⇒ x + x - 53 = 847
-------------------------------------------------------------- Solve x : -------------------------------------------------------------- x + x - 53 = 847 2x - 53 = 847 2x = 847 + 53 2x = 900 x = 450
-------------------------------------------------------------- Find cost of dryer and washer : -------------------------------------------------------------- Dryer = x = $450 Washer = x = 450 - 53 = 397
