Hi there,
\n" ); document.write( "Make the man's age = x
\n" ); document.write( "(x + 8) * 2 = 100 [* means times]
\n" ); document.write( "Now transpose the formula to leave x on its own
\n" ); document.write( "x + 8 = 100/2
\n" ); document.write( "x + 8 = 50
\n" ); document.write( "x = 50 - 8
\n" ); document.write( "x = 42
\n" ); document.write( "The man's present age is 42 years old.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
