There are 2 equations in this problem.
\n" ); document.write( "Let d= dimes
\n" ); document.write( "Let n= nickels
\n" ); document.write( "d+n=60
\n" ); document.write( "0.1d+0.05n=4
\n" ); document.write( "Use substitution to solve
\n" ); document.write( "n=60-d
\n" ); document.write( "0.1d+0.05(60-d)=4
\n" ); document.write( "0.1d+3-0.05d=4
\n" ); document.write( "0.05d=1
\n" ); document.write( "d=20
\n" ); document.write( "Now substitute d into one of the original equations
\n" ); document.write( "20+n=60
\n" ); document.write( "n=40
\n" ); document.write( "The girl has 20 dimes and 40 nickels
\n" ); document.write( "
\n" );
