It's saying that 66 equals to the total number of balls and nets. x = # of basketballs y = # of nets x + y = 66

So let's say we want to figure out the number of basketballs. $45b + $15n = $2610 $45b + $15n - $15n = $2610 - $15n $45b = $2610 - $15n

b+n=66 b= 58-1/3n 58-1/3n+n=66 (2/3)n= 8 n=12

b+12=66 b=54
