I'm assuming it looks like this:
0 > x + 5 > 5
so then the next step is to subtract 5 from every section.
-5 > x > 0
And there you go. :]
5*0 is 0
x is greater than or equal to 5.
X is greater than 5. If X were equal to 5, X-5 would be 0 which has no real square root. If X were 4, X-5 would be -1 which has no real square root, and so on.

(5, 0)
x2-5x = 0 x(x-5) = 0 x = 0 or x = 5
what is c, x + 2y, x+y equal to or greater than 8, x equal to or greater than 3, y equal to or greater than 0.
X >= -5
5*0 is 0
x is greater than or equal to 5.
X is greater than 5. If X were equal to 5, X-5 would be 0 which has no real square root. If X were 4, X-5 would be -1 which has no real square root, and so on.
x > -5

(5, 0)
6 x 0 x 5 = 0 Because any number multiplied by 0 is equal to zero, 6 x 0 = 0 and then 0 x 5 = 0.
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
0 <= x <= 6 gives -1 <= Y <= 14.
