Thus, I would rewrite the example above as x = y – 3 ⇔ Usually I do not deduct points for a sloppy handwriting style, provided that the student ends up with the right answer at the end -- but some students write so badly Brian: I like the idea of having one more equation than graph.

The solutions appear to be x=0 and x = -3. The "My Dear Aunt Sally" interpretation (multiplication, division, addition, subtraction): Perform multiplication before division.
