a number is divisible by 3 if the sum of its digits is divisible by 3. 375, for instance, is divisible by 3 since sum of its digits (3+7+5) is 15. And 15 is divisible by 3. 1+2=3 and 3 is divisible by 3
Not sure if you are just looking for equations but it would be written as
1/4(r+10)=r-4
Solving would be
1/4r+10/4=r-4
26/4=3/4r
r=26/3 or 8.66
