Let x = number of basketballs, and y = number of soccer balls. First, set up the given data in a table
|Forming machine||2 (min)||1||60 (min)|
|Inflating machine||1 (min)||1.5||60 (min)|
the 60's are there since both machines run constantly.
This leads to the system
which has solution (15, 30). Thus, you should make 15 basketballs and 30 soccer balls.
