Cramer's Rule says that:
Solve the following system; if the system is inconsistent say so. Use Cramer's Rule to obtain solution.
-9x + -4y + -6z = 85
-16x + -6y + 37z = 81
-7x + 8y + -4z = 75.
I am able to work this when there is just two sets of equations but I am having trouble figuring out three of them.
