Answer:
x=2, y=-1, z=3
Step-by-step explanation:
The system shown in the attached picture can be solved using any method you wish
I think that the best way to go is by using the subtraction method,
First multiply the equation x+y+z=4 by 2, then sum it to the second equation.
This gives another equation: 4x+z=11.
If we subtract the first eq. with the third, we have another eq. -5x+z=-7.
Lest sum the 2 new founded equations, to obtain the following result: -9x=-18
thus, we obtain x=2
Next lets go backwards in the prior eq -5x+z=-7, with x=2, we obtain that z=3
Now in the first equation (x+y+z=4) we can substitute x=2, z=3 to obtain y value.

Answer: approximately 2.11</h3>
Work Shown:
x = 108 is the raw score we want to transform
mu = 104 is the mean
sigma = 1.9 is the standard deviation
z = (x-mu)/sigma
z = (108-104)/1.9
z = 4/1.9
z = 2.10526315789473 which is approximate
z = 2.11 rounding to two decimal places
I'm rounding to two decimal places because many z tables will work with this level of precision.
