i used the equation: 1/2x+1/4x+3=x
then add 1/2x and 1/4x: 3/4x+3=x
then subtract 3/4x on both sides:3=1/4x
then divide by 1/4x: 12=x
12 coins is the answer :)

1/2 + 1/4 = 3/4
so 3/4 of his coins must be made up of pennies and quarters.
so that means the remaining 1/4 must be dimes
But we know that he has 3 dimes
think this way: 1/4 of what number is 3 ?
or
3 divided by 1/4 is .... ?
