You can put this solution on YOUR website!
x = number of dimes Jill has
\n" ); document.write( "y = number of dimes Joan has\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Jill has six times as many dimes as Joan\"
\n" ); document.write( "x = 6y\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "together they have a total of 84 dimes
\n" ); document.write( "x+y = 84\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+y = 84 ... focus on the first equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6y+y = 84 ... replace x with 6y (x = 6y)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7y = 84\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7y/7 = 84/7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use this to find x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 6y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 6*12 ... replace y with 12 (since y = 12 was found above)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 72\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jill has 72 dimes
\n" ); document.write( "
\n" );
