anonymous
  • anonymous
isnt there something we can work out
anonymous
  • anonymous
can we finish this at 3:30
terenzreignz
  • terenzreignz
Well then, your mom's going to have to wait
anonymous
  • anonymous
lol yeah
anonymous
  • anonymous
ok lets start
terenzreignz
  • terenzreignz
Okay. I'll try and make this quick. But this is not how it should be done, okay? haha
anonymous

okay

Suffice it to say, Fred only has 3/8 of John's money. We're looking for how much John originally had.
anonymous
  • anonymous
yes
terenzreignz
  • terenzreignz
So. John's original amount is x Fred's is 3/8 x
anonymous
  • anonymous
yes
terenzreignz
  • terenzreignz
Now if John gives Fred 6, his amount will become x - 6 because he loses 6, right? What happens to Fred's money?
anonymous
  • anonymous
he will gain 6
terenzreignz
  • terenzreignz
so his amount becomes...?
anonymous
  • anonymous
9
terenzreignz
  • terenzreignz
no. Where did you get that? haha His amount was originally 3/8 x so you just add 6 to that
anonymous
  • anonymous
6 3/8
terenzreignz
  • terenzreignz
\[\Large \frac38x + 6\] more like :P
terenzreignz
  • terenzreignz
So John's new amount is x - 6 and that thing up there ^ is Fred's new amount Apparently, with these new amounts, John has twice Fred's money. So, in equations, that'd be \[\Large x - 6 = 2\left[\frac38x + 6\right]\]
terenzreignz
  • terenzreignz
Now solve for x as you did last time
anonymous
  • anonymous
thats really confusing like last time lol
terenzreignz
  • terenzreignz
It's just the fraction. But actually, you just distribute the 2 to the two terms inside the [] much like you did with the 6 earlier.
anonymous
  • anonymous
x-6=6/8+12
anonymous
  • anonymous
is that correct
terenzreignz
  • terenzreignz
It is. You can multiply everything by 8 to get rid of that denominator.
terenzreignz
  • terenzreignz
And again, you missed a spot. x's don't just disappear XD
terenzreignz
  • terenzreignz
\[\Large x - 6 = 2\left[\frac38\color{red}x + 6\right]\]
anonymous
  • anonymous
i still don't get it can you just tell me what x is
anonymous
  • anonymous
please friend
anonymous
  • anonymous
friends are suppose to help friends
terenzreignz
  • terenzreignz
I have a name, you know LOL
anonymous
  • anonymous
please help me terence
anonymous
  • anonymous
what is x suppose to be
terenzreignz
  • terenzreignz
lol that's just an alias I've been using. I'll multiply by 8, you do the rest. You CAN do it, because you did it before lol 8x - 48 = 6x + 96 Now solve it.
anonymous
  • anonymous
plus 48 to both sides
anonymous
  • anonymous
???????????
terenzreignz
  • terenzreignz
Yup. You get...?
anonymous
  • anonymous
or minus 96 to both sides
terenzreignz
  • terenzreignz
Better to add 48 to both sides.
anonymous
  • anonymous
8x=6x+144
anonymous
  • anonymous
??
terenzreignz
  • terenzreignz
good. Next?
anonymous
  • anonymous
-6x to both sides
terenzreignz
  • terenzreignz
Okay. And you get...?
anonymous
  • anonymous
2x=144 which x equals 72 yes
anonymous
  • anonymous
!!!!!!!!!!!!!!
terenzreignz
  • terenzreignz
And that's the answer. See? You CAN do it. You don't need me to tell you the answer haha
anonymous
  • anonymous
