tutorsd6 : cost of soccerballs = \$ x
tutorsd6 : cost of jercey = \$ y
tutorsd6 : condition 1 : 2x + 3y = 86
tutorsd6 : x + y = 32 , or x = 32 - y
tutorsd6 : now substitute the value of x in 2x + 3y = 86
tutorsd6 : 2 ( 32 - y ) + 3y = 86
tutorsd6 : 64 - 2y + 3y = 86
tutorsd6 : y = 86 - 64 = 22
tutorsd6 : x = 32 - 22 = \$ 10
tutorsd6 : 1 soccer ball cost = \$ 10
