You can put this solution on YOUR website! Let's first turn this into an equation. We are told 48 divided by the sum of 5 and a certain number we will call x equals three. This gives:
From here, we just need to isolate and solve for x. This is done as follows:
1) Multiply by both sides to get it out of the denominator:
2) Distribute the three to the binomial:
3) Subtract 15 from both sides:
4) Divide both sides by 3:
Finally verify we are correct by dividing 48 by 16 (the sum of 5 and x, our solution) to get 3.
