x = Queenie's age today
<table border = "1" cellpadding = "5"><tr><td></td><td>Paula</td><td>Queenie</td></tr><tr><td>Today</td><td>2x</td><td>x</td></tr><tr><td>Seven years ago</td><td>2x-7</td><td>x-7</td></tr></table>
Add the expressions in the bottom row. That sum is 16.


(2x-7) + (x-7) = 16
3x-14 = 16
3x = 16+14
3x = 30
x = 30/3
x = 10


Answer: Queenie is 10 years old.
