William says to Gracie, "If you give me $5.50, we will have an equal amount of money."
Gracie responds, "That may be true, but if you give me $5.50 instead, I will have twice as much money as you."
How much money did William and Gracie each have in the beginning?
:
Let w = W's original amt
Let g = G's original amt
:
Write an equation for each statement, simplify as much as possible.
:
"William says to Gracie, "If you give me $5.50, we will have an equal amount of money."
w + 5.50 = g - 5.50
w = g - 5.50 - 5.50
w = g - 11
:
Gracie responds, "That may be true, but if you give me $5.50 instead, I will have twice as much money as you"
g + 5.50 = 2(w-5.50)
g + 5.50 = 2w - 11
g - 2w = -11 - 5.50
g - 2w = -16.50
replace w with (g-11)
g -2(g-11) = -16.50
g - 2g + 22 - 16.50
-g = 16.50 - 22
-g = -38.50
g = 38.50 is G's original amt
find w
w = 38.50 - 11
w = 27.50 is W's original amt

You can confirm this for yourself, try these value in both statements
