3 over 5 x minus 15 = 6 over 5 x plus 12

3/5x - 15 = 6/5x +12
-3/5x+3/5x-15=6/5x-3/5x+12 subtraction property
-15=3/5x+12 simplified
-12-15=3/5x+12-12 subtraction property
-27=3/5x simplified
(5/3)(-27)=3/5 (5/3)x multiplicative inverse
-45=x

$\frac{a}{b}=\frac{5}3}\\\\a=\frac{5}{3}b$

For every one ball, there 5 thirds of a racket.

We plot this function on a graph to visualize our model;
