Let the number be x\r
\n" ); document.write( "\n" ); document.write( "We derive the equation x+9 = 3x-1
\n" ); document.write( " 3x-1 = x+9
\n" ); document.write( "Taking variable to RHS, 3x-x-1 = 9
\n" ); document.write( "Taking constant to LHS 2x = 9+1
\n" ); document.write( " ie, 2x = 10
\n" ); document.write( " x = 10/2 = 5\r
\n" ); document.write( "\n" ); document.write( "The number is 5.
\n" ); document.write( "
\n" );
