x + y +z = 6..........(1)

z = x + y...............(2)

x = z + 1................(3)

from  equation (2) :-

x + y = -z

Subtracting this from equation (1) :-

z = -z  + 6

2z =  6  so z = 3

From equation (3) :-

x = 3 + 1 =  4

And from equation (1):-

4 + y + 3 = 6

y = 6 - 7 = -1

Answer  x = 4, y = -1 and z = 3.

How do you do this question?
daser333 [38]

Answer:

B. 1/2

Step-by-step explanation:

\lim_{z \to 0} \frac{g(z)e^{-z}-3}{z^{2}-2z}

If we plug in 0 for z, we get 0/0.  Apply l'Hopital's rule.

\lim_{z \to 0} \frac{-g(z)e^{-z}+g'(z)e^{-z}}{2z-2}

Now when we plug in 0 for z, we get:

\frac{-g(0)e^{0}+g'(0)e^{0}}{2(0)-2}\\\frac{-g(0)+g'(0)}{-2}\\\frac{-3+2}{-2}\\\frac{1}{2}
