no. of dimes=x
\n" ); document.write( "no. of quarters = y\r
\n" ); document.write( "\n" ); document.write( "from 1st condition,
\n" ); document.write( "x*.10+y*.25=30.50\r
\n" ); document.write( "\n" ); document.write( "from 2nd condition,
\n" ); document.write( "x-4=y\r
\n" ); document.write( "\n" ); document.write( "substitution value of y in 1st equation,\r
\n" ); document.write( "\n" ); document.write( "x*10+(x-4)*25=30.50
\n" ); document.write( "solving we get
\n" ); document.write( "no. of dimes :90
\n" ); document.write( "no.of quater: 86
\n" ); document.write( "
