You can put this solution on YOUR website!
Let the number be x and y
\n" ); document.write( "as per the question
\n" ); document.write( "x+y = 49 - (eq1)
\n" ); document.write( "x-y = 25 - (eq2)\r
\n" ); document.write( "\n" ); document.write( "adding eq1 and eq2 we have\r
\n" ); document.write( "\n" ); document.write( "x+y = 49
\n" ); document.write( "x-y = 25
\n" ); document.write( "------------
\n" ); document.write( "2x = 74
\n" ); document.write( "x = 74/2 = 37
\n" ); document.write( "putting the value in equation 1 we have\r
\n" ); document.write( "\n" ); document.write( "37 + y = 49
\n" ); document.write( "y = 49-37 = 12\r
\n" ); document.write( "\n" ); document.write( "so x = 37 and y = 12 (Ans)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
