Another math problem, problem. Please help me?

Question

I stink at math- as you can probably tell, so now I need help again.

HERE IS THE PROBLEM:

Replace x,y, and z with integers to show that (x-y) - z = x- ( y-z) is not true for all integers. If you can help me get the problem right and get it right- hopefully. Than you get easy points.

Answer 1

Replace each variable with "1."

-1 = 1  - not true.

Answer 2

x= 1

y= 2

z= 3

(1-2) - 3 = 1 - (2-3)

(-1) -3 = 1 -(-1)

-4 = 2

therefore; not true for all integers

Answer 3

(2-1)-0=2-(1-0)

so x=2.y=1,z=0

the equation is true in this case.

But for x=4,y=5,z=6

(4-5)-6=4-(5-6)

-7 is not equal to 5

Answer 4

x=5, y=5, z=5

(5-5)-5=5-(5-5)  --->  0-5=5-0

so there for

-5 does not equal +5

hope this helps

Answer 5

The equation is not true for integers x = 1, y = 2, z = 3

(1-2)-3 = -4

1-(2-3) = 2

Answer 6

x=3, y=2, z=1.

(3-2)-2=3-(2-1)

1-1=3-2

0=1

Not True
