Larry had 1/4 as many postcards as Noah. When Noah gave 50% of his postcards to Larry, he had 12 fewer postcards than his friend. How many postcards did Noah have at first?

Let Cards of Noah = x

      Cards of Larry = x/4

      Noah gave 50% to Larry than

           x - x/2 = x/4 + 12

          (2x - x)/2 = x/4 + 12

           x/2 = (x + 48)/4

           4x = 2x + 96

           4x - 2x = 96

               2x = 96

                 x = 48

Noah's Cards = 48
