n = number of nickels
\n" ); document.write( "5n = value of nickels in cents
\n" ); document.write( "d = number of dimes
\n" ); document.write( "10d = value of dimes in cents
\n" ); document.write( ".
\n" ); document.write( "5n + 10d = 305 cents
\n" ); document.write( ".
\n" ); document.write( "n = d+10
\n" ); document.write( ".
\n" ); document.write( "substitute
\n" ); document.write( ".
\n" ); document.write( "5(d+10) + 10d = 305
\n" ); document.write( ".
\n" ); document.write( "5d +50 +10d = 305
\n" ); document.write( ".
\n" ); document.write( "15d = 255
\n" ); document.write( ".
\n" ); document.write( "d = 255/15 = 17
\n" ); document.write( ".
\n" ); document.write( "n = d+10 = 27
\n" ); document.write( ".
\n" ); document.write( "Check the values to be sure this is the answer.
\n" ); document.write( ".
\n" ); document.write( "5(17) = 85
\n" ); document.write( "10(27) = 270
