Call the required number x.
\n" ); document.write( "Five times the number is 5x.
\n" ); document.write( "If this is 21 less than something then add on 21 so it will be equal to it.
\n" ); document.write( "5x + 21 =
\n" ); document.write( "The opposite of the number is (-x). Twice that will be 2*(-x)
\n" ); document.write( "So 5x + 21 = 2*(-x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x + 21 = -2x
\n" ); document.write( "Add 2x to both sides of the equation
\n" ); document.write( "5x + 26 + 2x = -2x + 2x
\n" ); document.write( "7x + 21 = 0
\n" ); document.write( "Subtract 21 from each side of the equation
\n" ); document.write( "7x + 21 - 21 = 0 - 21
\n" ); document.write( "7x = -21
\n" ); document.write( "x=-21/7
\n" ); document.write( "x=-3
\n" ); document.write( "Check if this meets the original conditions.
\n" ); document.write( "
\n" );
