Answer 4

Where are you starting from?

Answer 9

As best I can follow, variable z was eliminated at the start.

Then, variable y was eliminated.

It appears to me that what is left is two equations with 3 different variables among the two equations.

I would go back to equations 2 and 3 and eliminate the same variable z.

Then, you will be left with two equations in two unknowns which should work out.
