Question 58918
Let W be Will Clark cards , J be Jose Canseco cards and N be Nolan Ryan cards
Given that 6W + 3J = 2N  ----------(1)
and        12W + 2N = 9J   ----------------(2)
multiplying (1) by 2 gives 12W + 6J = 4N -----------------(3)
                           12W - 9J = - 2N ---------------(2) rearranged

Subtracting the above two equations we have, 6J + 9J = 4N + 2N
                                     ==>   15J = 6N
                                    ==>  5J = 2N [Dividing both the sides by 3]

Therefore 2 Ryan cards = 5 Canseco cards
