Hi there,
\n" ); document.write( "A number = 'x'
\n" ); document.write( "Double the number = 2x
\n" ); document.write( "Take away 20 = 2x - 20
\n" ); document.write( "You get 50 = 2x - 20 = 50
\n" ); document.write( "2x - 20 = 50
\n" ); document.write( "Collect like terms
\n" ); document.write( "2x = 50 + 20
\n" ); document.write( "2x = 70
\n" ); document.write( "x = 35
\n" ); document.write( "Number is 35
\n" ); document.write( "Hope this helps :-)
