Question 603080: Logan and Izzy had the same number of stickers. After Izzy gave him 72 stickers, Logan had 3 times as many stickers as Izzy. How many stickers did they have altogether?
I don't know how to do this. Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! Let the number of sticker each one initially had be x, and both together had 2x stickers.
After Izzy gives Logan 72 stickers,
Izzy has x-72 and
Logan has x+72.
They tell us that
x+72=3(x-72)
Multiplying (distributive property, we get the equivalent equation
x+72=3x-216
Adding 216 to both sides of the equal sign, we get
x+72+216=3x-216+216 --> x+288=3x
Subtracting x from both sides, we get
x+288-x=3x-x --> 288=2x
Logan and Izzy had initially had stickers between the two of them.
