You collect baseball and football cards. Your uncle has an old collection of 360 cards that he gives to you. The collection has more baseball cards than football cards. In fact, it has 30 more baseball cards than twice the number of football cards. Write a system of linear equations to help solve for how many of each type are in your uncle's collection.

let f = #footbal cards 22+ 30+ f = 360 b + f = 360. 34 +30 - 360. -30 -30 b=2f +30 b=2f+30.
