Equation form - x=3, y=-1

I hope this is what you were asking for. I just did Addition/Elimination. I don't know what you were looking for but I did this and got the answer. I hope this helps you and good luck!

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
