**Ms. Sue**, Sunday, February 5, 2012 at 1:41pmLet x = total number of coins.

1/2x + 1/4x + 3 = x

3 = x - 3/5x

3 = 1/4x

3 / (1/4) = x

3 * 4 = x

12 = x

**Reiny**, Sunday, February 5, 2012 at 1:43pmlet the number of coins he has be x

x/2 + x/4 + 3 = x

times 8

4x + 2x + 24 = 8x

2x = 24

x = 12

12/2 = 6 pennies

12/4 = 3 quarters

+ 3 dimes

= 12 coins

(A better question would have been:

How much money does Bobby have with his coins? )
