Question 1047653

Kathy is six years older than her cat. Next year she will be twice as old as her cat will be. How old is Kathy now?
<pre>Kathy is: {{{highlight_green(matrix(1,2, 11, years-old))}}}
How on earth could Kathy be 18 months-old when she is 6 years older than the cat. What does that make the cat: 18 months, less 6 years?
Isn't that {{{matrix(1,2, - 4&1/2, years)}}}? How can something have an age of {{{matrix(1,2, - 4&1/2, years)}}}?  
Why do these people respond and give these stunningly RIDICULOUS answers.
