x= one number
\n" ); document.write( "y= second number
\n" ); document.write( "
\n" ); document.write( "1 x + 1 y = 36 .............1
\n" ); document.write( "
\n" ); document.write( "1 x -1 y = 4 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "Add the two equations
\n" ); document.write( "2 x = 40
\n" ); document.write( "/ 2
\n" ); document.write( "x = 20
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 36
\n" ); document.write( "20 + y = 36
\n" ); document.write( " y = 36 -20
\n" ); document.write( " y = 16
\n" ); document.write( " y = 16 1
\n" ); document.write( "x= 20 one number
\n" ); document.write( "y= 16 second number
