Question 1121728
Susan is 3 inches taller than her mom. Susan's sister is 2 1/3 feet 
    shorter than her and 8/13 the height of her mother. How tall is
    Susan's mom?
<pre>Mom's height: {{{highlight_green(matrix(1,4, 5, feet, 5, inches))}}}
You'll NEVER get this answer if you try to solve the equation the other person gave you to solve. NEVER, in a million years!
That equation is: {{{cross((x+3)-2&1/3=x(8/13))}}}
