Well you would have to set up the equation first. X is going to equal the price of the dryer. The equation that would be set up then is 3x + x = 1160. Then you add the common numerals, in this case 4x = 1160. Then you would divide, which gives you x = 290 The dryer costs $290. Then you would multiply the dryer price by 3, because the washer is 3 times as much as the dryer. And finally, you get: Dryer = $290 Washer = $870
