Answer:
24
The problem:
If
, what is the value of
?
Explanation:
![\frac{1}{2}x+\frac{1}{3}y=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dx%2B%5Cfrac%7B1%7D%7B3%7Dy%3D4)
I would like to clear the fractions.
You can do this by multiplying both sides by a common multiple of your denominators; preferably the least common multiple.
So the least common multiple of 2 and 3 is 6.
So I'm going to multiply both sides by 6:
![6(\frac{1}{2}x+\frac{1}{3}y)=6(4)](https://tex.z-dn.net/?f=6%28%5Cfrac%7B1%7D%7B2%7Dx%2B%5Cfrac%7B1%7D%7B3%7Dy%29%3D6%284%29)
Distribute and multiply:
![\frac{6(1)}{2}x+\frac{6(1)}{3}y=24](https://tex.z-dn.net/?f=%5Cfrac%7B6%281%29%7D%7B2%7Dx%2B%5Cfrac%7B6%281%29%7D%7B3%7Dy%3D24)
![\frac{6}{2}x+\frac{6}{3}y=24](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B2%7Dx%2B%5Cfrac%7B6%7D%7B3%7Dy%3D24)
![3x+2y=24](https://tex.z-dn.net/?f=3x%2B2y%3D24)
So the value of
with the given condition is 24.
