Subtract 7 to 28 = 21 then divided by -3 = x= -7
Answer:
9
Step-by-step explanation:
jerry-3 = molly
molly = 6
jerry - 3 = 6
jerry = 9
Dryer cost represented by x
Then, the washer costs (x + $72)
Together, they cost (x) + (x+72) = $772
2x+72 = 772
[subtract 97 from both sides]
x = 350
[divide both sides by 2]
The dryer cost $350
The washer cost $422.
Together, they cost $772
