Answer:

The dryer cost 325

Step-by-step 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
