You don't have to make this a COMPLEX solution by creating 2 separate variables. So, proceed as follows:
\n" );
document.write( "Let Jill's age be J
\n" );
document.write( "Then Jack's is 2J
\n" );
document.write( "We then get: 2J + 5 = 1.5(J + 5)
\n" );
document.write( "2J + 5 = 1.5J + 7.5
\n" );
document.write( "2J - 1.5J = 7.5 - 5
\n" );
document.write( ".5J = 2.5
\n" );
document.write( "Jill's age, or \"highlight_green%28matrix%281%2C5%2C+J%2C+%22=%22%2C+2.5%2F.5%2C+%22=%22%2C+5%29%29\"
\n" );
document.write( "You should now be able to find Jack's age! \n" );
document.write( "
\n" );
