           Summary: Directions ask for an "expression" when an equation is
                    required

Parts (a) and (b) of this problem each ask for "a mathematical expression" for
a certain quantity.  However, the problem wants to receive an equation.  For
example, with the given seed, the expected answer is some equation equivalent
to:
    x + y = 137.
However if you take the directions literally, then either "x+y" or "137" would
be a correct answer, and the equation above would not be.

I cannot think of an ideal way to fix the directions to (a) and (b).  The best
I can come up with is to change "a mathematical expression" to "an equation
involving x and y".

Also, "Use" should be "use".
