Do you have any clue?
anonymous
  • anonymous
I have no clue
Defiance
  • Defiance
Alright. Lets get started then.
Defiance
  • Defiance
First, find the least common denominator.
Defiance
  • Defiance
Left is 12, right is 5.
Defiance
  • Defiance
5 x 12 = 60 For this case is the lowest.
Defiance
  • Defiance
Rewright them.
Defiance
  • Defiance
So times the rightside by 5 and the left bu 12.
anonymous
  • anonymous
k
Defiance
  • Defiance
\[\frac{ 15y-8 }{ 60}\] = \[\frac{ y }{ 60 }\]
anonymous
  • anonymous
ok I understand so far
Defiance
  • Defiance
Okay, so subtract 40 from both sides.
anonymous
  • anonymous
why would I subtract 40? That confuses me
Defiance
  • Defiance
Okay, lets do it another way sorry.
Defiance
  • Defiance
Lets start with making y/5 = 0.
Defiance
  • Defiance
Pretend the right side is 0.
Defiance
  • Defiance
\[\frac{ 3y - 8 }{ 12 } - \frac{ y }{ 5 }\] \[= \frac{ y }{ 5 } - \frac{ y }{ 5 } = 0\]
Defiance
  • Defiance
Subtract y / 5 from both sides.
Defiance
  • Defiance
To make the right = 0
anonymous
  • anonymous
ok
Defiance
  • Defiance
(3y-8)/12-(y/5) = 0
Defiance
  • Defiance
\[\frac{ 3y - 8 }{12 - \frac{ y }{ 5 } }\]
anonymous
  • anonymous
we wouldn't be subtracting y from the 3y up top and the 5 from the 12 down below?
Defiance
  • Defiance

anonymous
  • anonymous
sorry I just am really confused
Defiance
  • Defiance
OKAY... Cross multiply... You know how to do that right?
anonymous
  • anonymous
ya
Defiance
  • Defiance
\[5(3y-8) =12y\]
Defiance
  • Defiance
Solve that.
Defiance
  • Defiance
You get \15y - 40 = 12y\]
anonymous
  • anonymous
k
Defiance
  • Defiance
\[15y - 40 = \]
Defiance
  • Defiance
12y
Defiance
  • Defiance
You get the 40 cause you cross multiplied 5 to 8.
anonymous
  • anonymous
yes
Defiance
  • Defiance
Can you solve form here? Or no.
anonymous
  • anonymous
would I subtract 15y to isolate the y on the on the 12y side?
Defiance
  • Defiance
Move the 12y over to the 15y. To get \[15y -12y = 40\]
anonymous
  • anonymous
ok
Defiance
  • Defiance
Solver it. Which is simple \[3y = 40\]
Defiance
  • Defiance
Move the 3 back to the 40 to make the faction.
anonymous
  • anonymous
ok so now I just subtract 3 from both sides to get y=37?
Defiance
  • Defiance
40/3
Defiance
  • Defiance
No.
Defiance
  • Defiance
The faction is 40/3
anonymous
  • anonymous
ok nm I just saw your other posts
Defiance
  • Defiance
The answer is \[40/3 or 13.33\]
anonymous
  • anonymous
k
Defiance
  • Defiance
either one. 13.33 is 40/3 as a decimal.
anonymous
  • anonymous
Thank you and I am sorry that I was such a pain
Defiance
  • Defiance
3y-8/12 = y /5 5( 3y - 8) = 12y 15y -40 =12y 15y -12y =40 3y=40
Defiance
  • Defiance
That just to show the math.
Defiance
  • Defiance
And it's fine, anything to help. It's what I'm here for ;)
