You can put this solution on YOUR website!
n = d+30 since he has 30 more nickels than dimes, to make them equal you have to add 30 to the dimes.

\n" ); document.write( "n+d = 150 substitute for n:
\n" ); document.write( "d+30+d = 150
\n" ); document.write( "2d = 120
\n" ); document.write( "d = 60 he has 60 dimes and 150-60 = 90 nickels\r
