We are to find the number of hits Billy and Ryan had in this game. We are then to find 2 thing or in other words there are 2 variables that we have to solve. As a rule we need to find 2 relationships. The 2 relationships or equations are:
B + R = 99
[tex] \frac{B}{R} = \frac{7}{4} [/tex] or 4B - 7R = 0
where B- Billy's hit and R - Ryan's hit.
B= 63
R=36
