Question #0e732

Answer 1

`64`

Explanation:

Let `x` be the number of baseball cards Fred began with.

`x + 6 = 2xx35`

`=70 - 6= 64`

Fred had 64 cards, he then bought 6 to bring his collection up to 70, then his dog ate half leaving him with 35.

To figure out how many cards he originally had, you must double the number of cards left (which brings you back to 70), then subtract 6 for the cards he bought. This leaves you with 64.
