Let x and y are two numbers\r
\n" ); document.write( "\n" ); document.write( "x+y=62 .....(1)
\n" ); document.write( "x-y=16......(2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add (1) and (2)
\n" ); document.write( "x+y=62 .....(1)
\n" ); document.write( "x-y=16......(2)
\n" ); document.write( "--------
\n" ); document.write( "2x=78\r
\n" ); document.write( "\n" ); document.write( "x=78/2
\n" ); document.write( "x=39\r
\n" ); document.write( "\n" ); document.write( "Put the value of x in (1) or (2) we have
\n" ); document.write( "39+y=62
\n" ); document.write( "y=62-39
\n" ); document.write( "y=23
\n" ); document.write( "Numbers are 39 and 23
\n" ); document.write( "Check
\n" ); document.write( "x-y=16
\n" ); document.write( "39-23=16
\n" ); document.write( "16=16
\n" ); document.write( "and
\n" ); document.write( "x+y=62
\n" ); document.write( "39+23=62
\n" ); document.write( "62=62\r
