Rearrange p=r+3 to make r the subject

In this case, we have this equation:

p = r + 3

And we need to get r, so we will need to have only r at a side.

We can just substract 3 from both sides and get

p - 3 = r

And we know that r = p-3

76%

24% are dogs and the remaining is 76% because 100-24=76
