x + y = 65
\n" ); document.write( "x = y + 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute the second equation into the first equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(y + 9) + y = 65
\n" ); document.write( "2y + 9 = 65
\n" ); document.write( "2y = 56
\n" ); document.write( "y = 28\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution: (x, y) = (37, 28)
\n" ); document.write( "
\n" );
