Let the number of footballs cards Alison have be "x".
It is given that Allison has 5 times as many baseball cards as football cards which can be represented by an expression given by
number of baseball cards = 5 × number of football cards
number of baseball cards
...(1)
She has total of 120 baseball and football cards which can be represented by an expression given by
Baseball cards + football cards = 120
![5x+x=120\\6x=120\\x=20](https://tex.z-dn.net/?f=5x%2Bx%3D120%5C%5C6x%3D120%5C%5Cx%3D20)
From equation (1) , put x = 20 we get
Baseball cards = ![5\times20](https://tex.z-dn.net/?f=5%5Ctimes20)
