Answer:
The dryer cost 325
Explanation:
Let w = the cost of the washer
d = cost of the dryer
w+d = 701
w = d+51
Replace w in the first equation with d+51
d+51 +d = 701
Combine like terms
2d+51 = 701
Subtract 51 from each side
2d+51-51 = 701 -51
2d = 650
Divide by 2
2d/2 = 650/2
d = 325
The dryer cost 325
