Answer:
5.5 years old.
Step-by-step explanation:
Let D represent present age of Robert's dog and C represent present age of Karen's cat.
We have been given that Robert's dog is 4 years older than Karen's cat. We can represent this information in an equation as:
![D=C+4...(1)](https://tex.z-dn.net/?f=D%3DC%2B4...%281%29)
We are also told that in 3 years, the sum of the ages of Robert's dog and Karen's cat will be 13. After 3 years age of dog and cat would be
and
respectively.
We can represent this information in an equation as:
![D+3+C+3=13...(2)](https://tex.z-dn.net/?f=D%2B3%2BC%2B3%3D13...%282%29)
From equation (1), we will get:
![C=D-4](https://tex.z-dn.net/?f=C%3DD-4)
Upon substituting this value in equation (2), we will get:
![D+3+D-4+3=13](https://tex.z-dn.net/?f=D%2B3%2BD-4%2B3%3D13)
Combine like terms:
![2D+2=13](https://tex.z-dn.net/?f=2D%2B2%3D13)
![2D+2-2=13-2](https://tex.z-dn.net/?f=2D%2B2-2%3D13-2)
![2D=11](https://tex.z-dn.net/?f=2D%3D11)
![\frac{2D}{2}=\frac{11}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2D%7D%7B2%7D%3D%5Cfrac%7B11%7D%7B2%7D)
![D=5.5](https://tex.z-dn.net/?f=D%3D5.5)
Therefore, Robert's dog is 5.5 years old right now.
