math word problem

kevin sold half of his baseball cards to miles and then went into the mall and bought 12 more he has 65 baseball cards in his collection write an equation to find out how many baseball cards kevin started with

Kel M.

The original number of cards is going to be our x. He sold half, so we'll start out with x/2 (x divided by 2). Let's put away our x/2 in parentheses so that we know it goes first under PEMDAS. Then he bought 12 more. (x/2) + 12 = 65. You were only asked to write the equation, but let's solve it too, just for fun. I'm going to first subtract the +12 from both sides of the equals sign. Now we're left with: (x/2) = 53. Now we can forget the parentheses and get rid of that "divided by two." To do that, we'll multiply by two on both sides of the equals sign instead. x = 106 baseball cards.
