To find r, first write out the equation:
![\frac{3r+4}{2} =5](https://tex.z-dn.net/?f=%20%5Cfrac%7B3r%2B4%7D%7B2%7D%20%3D5)
Next, multiply both sides by 2:
![3r+4=10](https://tex.z-dn.net/?f=%203r%2B4%3D10)
Now, subtract both sides by 4:
![3r = 6](https://tex.z-dn.net/?f=%203r%20%3D%206)
Divide both sides by 3:
![r=2](https://tex.z-dn.net/?f=r%3D2)
The answer to this problem is
r = 2. Hope this helps and have a phenomenal day!
