x + y = 312
\n" ); document.write( ".......
\n" ); document.write( "x - y = 38
\n" ); document.write( "x = 38 + y
\n" ); document.write( "Substitute x = 38 + y
\n" ); document.write( "into x + y = 312
\n" ); document.write( "38 + y + y = 312
\n" ); document.write( "38 + 2y = 312
\n" ); document.write( "2y = 312 - 38
\n" ); document.write( "2y = 274
\n" ); document.write( "y = 137
\n" ); document.write( "Substitute y = 137
\n" ); document.write( "into x + y = 312
\n" ); document.write( "x + 137 = 312
\n" ); document.write( "x = 312 - 137
\n" ); document.write( "x = 175
\n" ); document.write( "Two numbers are:
