Answer:
b. (2, 5, 3)
Step-by-step explanation:
Trying the offered choices seems the fastest way to find the answer. The second choice works in all equations, hence is the solution.
Another strategy you can use is to see if the equations are dependent. Here, it looks like adding twice the third equation to the other two eliminates at least the x- and y-variables. If that eliminates z, then there are infinite solutions. Instead, it gives the equation ...
7z = 21
z = 3 . . . . . divide by 7
This answer is consistent with choice B, confirming that answer and eliminating the other choices.

A) from 2 to infinity
B) from -infinity to -3
C) -3 to 2
D) -infinity to -3 and 2 to infinity
E) -infinity to infinity
F) no because the slope is linnear in 2 stops but has a different slope in both spots meaning it can’t be a linnear function or an exponential funtion
