c. x ≈ 1.71, y ≈ 6.29, z ≈ 60.71
Step-by-step explanation:
You are at a bit of a disadvantage with this problem, because both the hint and the answer choices are incorrect.
The matrix equation is ...
Contrary to what the hint is telling you, the multiplication by the inverse must be on the left:
Using appropriate tools to compute the inverse, this becomes ...
The closest match is choice C.
