The other way you can do it is to plug in the numbers into each equation and see what works.
(0,100) so x=0, y=100. Plugging them into the equations...Bummer - A, B, C, D, E are all true
Only A and B are true
We only have to look at A and B and only A is true so that must be the answer.
(96 doesn't equal 100-2)
