d = costs of the dryer
w = costs of the washer
A washer and dryer costs $745 combined, means:
w + d = 745
The washer costs $45 more than the dryer means:
w = d + 45
Replace this value in first equation
w + d = 745
d + 45 + d = 745
2 d + 45 = 745
Subtract 45 to both sides.
2 d = 700
d = 700 / 2 = 350
Costs of the dryer = $350
w = d + 45 = 350 + 45 = 395
Costs of the washer = $395
w = costs of the washer
