\n" ); document.write( "Does this question have 1 variable or two?
\n" ); document.write( "Three years ago tom was twice as old as jean. And in two years the sum of their ages will be 28 years. Find their present ages.\r

You can use either. I prefer to use ONLY 1. 
\n" );
document.write( "In this case, I'd let Jean's age be J
\n" );
document.write( "Then, 3 years ago, Jean was J - 3
\n" );
document.write( "Therefore, Tom's age then, was: 2(J - 3), or 2J - 6, which makes Tom's current age: 2J - 6 + 3, or 2J - 3
\n" );
document.write( "We then get: J + 2 + 2J - 3 + 2 = 28
\n" );
document.write( "Solve for J, Jean's current age.
\n" );
document.write( "Then calculate: 2J - 3 for Tom's current age. \n" );
document.write( "

\n" );
