Answer:
Eve has $5
Adam has $7
Explanation:
let Eve's money = x
Adam's money = y
Eve said to Adam, “if you give me a dollar, then we will have the same amount of money
We can make this equation
x + 1 = y + 1
Eve, if you give me one dollar, I will have double the amount of money you are left with.
We can make this equation
y + 1 = 2(x - 1)
y + 1 = 2x - 2
y = 2x - 3
If x + 1 = y + 1, then
x + 1 = 2x - 3 - 1
x - 2x = -3 -1 -1
-x = -5
x = 5 Eve has $5
Since y = 2x - 3
y = 2(5) - 3
y = 10 - 7
y = 7 Adam has $7
