Which point is not a solution to the system of inequalities? y > x – 5 y ≤ –x + 3

Y > x - 5 and y <= -x +3  so we need getting the value of x what not is common root of every two inequalities 

for x = 5 
the first inequality will be y > 5-5 so y > 0 so this mean that result the point
with coordinates [5,0)
and the second inequality for x = 5 will be y <= -5 +3 so y <= -2 so what mean
that result the point with coordinates [5,-2]

so x=5 not is a solution to the system
