is it? let's check.
x-5>3 x = 10
(10) - 5 > 3
5 > 3 <----- hmmm is that really true? 5 is indeed greater than 3.
let's check the other condition, "y" being -10.
-y > 7 y = -10
-(-10) > 7
+10 > 7 <---- is 10 greater than 7 really? well, yes it is.
since the coordinates of 10, -10, provide a "true" value for each inequality, then 10,-10 is a solution.
