---- Used cranberry
Take LCM
![\frac{3c + 4c}{9} = 7](https://tex.z-dn.net/?f=%5Cfrac%7B3c%20%2B%204c%7D%7B9%7D%20%3D%207)
![\frac{7c}{9} = 7](https://tex.z-dn.net/?f=%5Cfrac%7B7c%7D%7B9%7D%20%3D%207)
Solve for c
![c= 7 * \frac{9}{7}](https://tex.z-dn.net/?f=c%3D%207%20%2A%20%5Cfrac%7B9%7D%7B7%7D)
![c= 9](https://tex.z-dn.net/?f=c%3D%209)
