Answer:
it either x = 10 or x = 1
Step-by-step explanation:
Time taken by Ria to paint a room = 4 hours
Time taken by Destiny to paint a room = 6 hours
If they work together, they complete 1 job. So,
![\frac{1x}{4}+\frac{1x}{6}=1](https://tex.z-dn.net/?f=%5Cfrac%7B1x%7D%7B4%7D%2B%5Cfrac%7B1x%7D%7B6%7D%3D1)
The LCD of 4 and 6 is 12
![\frac{3x+2x}{12}=1](https://tex.z-dn.net/?f=%5Cfrac%7B3x%2B2x%7D%7B12%7D%3D1)
![\frac{5x}{12}=1](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B12%7D%3D1)
![5x=12](https://tex.z-dn.net/?f=5x%3D12)
![x=\frac{12}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%7D%7B5%7D)
Hence, both of them can paint the room in
hours or 2.4 hours.
