by the number of months
![75+10x=50+15x](https://tex.z-dn.net/?f=75%2B10x%3D50%2B15x)
![10x=15x-25](https://tex.z-dn.net/?f=10x%3D15x-25)
![-5x=-25](https://tex.z-dn.net/?f=-5x%3D-25)
![\frac{-5x}{-5}=\frac{-25}{-5}](https://tex.z-dn.net/?f=%5Cfrac%7B-5x%7D%7B-5%7D%3D%5Cfrac%7B-25%7D%7B-5%7D)
![x=5](https://tex.z-dn.net/?f=x%3D5)
