Question 1108593
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:
{{{48/(5+x)=3}}}

From here, we just need to isolate and solve for x. This is done as follows:
1) Multiply {{{(5+x)}}} by both sides to get it out of the denominator:
{{{48=3(5+x)}}}
2) Distribute the three to the binomial:
{{{48=15+3x}}}
3) Subtract 15 from both sides:
{{{33=3x}}}
4) Divide both sides by 3:
{{{x=11}}}

Finally verify we are correct by dividing 48 by 16 (the sum of 5 and x, our solution) to get 3.
