You can put this solution on YOUR website!
From the answer you came up with, I think you meant that there was 150 nickles and dimes not 50. So I changed your question, if I'm wrong let me know.
\n" ); document.write( "This is a pretty tough question for a third grader. Your son must be pretty smart.
\n" ); document.write( "Let the number of dimes=x
\n" ); document.write( "Let the number of nickels=x+70
\n" ); document.write( "If we add the nickels and dimes together=150
\n" ); document.write( "Your problem to solve is:
\n" ); document.write( "x+x+70=150
\n" ); document.write( "(1+1)x+70=150
\n" ); document.write( "2x+70=150
\n" ); document.write( "2x+70-70=150-70
\n" ); document.write( "2x=80
\n" ); document.write( "2x/2=80/2
\n" ); document.write( "x=40
\n" ); document.write( "The number of dimes=x=40
\n" ); document.write( "The number of nickles=x+70=40+70=110
\n" ); document.write( " \n" ); document.write( "
\n" );
