8x + 48 = 6x + 72
So anyway set them equal to each other because the problem says they both have an equal amount of me on X number of days. Therefore you have to solve for X in this problem
I see so when it says "How many days will Joel have as much money as Alaina that means how many days will they have equivalent (=) money right?

What I would do is subtract 6x from both sides and subtract 48 from both sides you get 2x = 24 divide by two and x = 12
Therefore in 12 days they will both have the same amount of money. you did it (;
In my head
So if i graphed it, what would be the point where they have same amount of money
It would be helpful if you asked your second question :P
according to my calculations if your asking how much money they would both have it would be (12, 144)
Alaina has $72 and earns $6 each day, Joel has $48 and earns $8 each day. In How many days will joel have as much money as Alaina?
A=J (Alaina and Joel must have the same ammount of money)
(72+6D)($) = (48+8D)*($) (note that system units is $-money and simplifies at the end)
