Question 252267: Can cramer's rule be used for: if so what would I use for the middle equation for the coefficient of y and what would the constant be...???
x+y+z=2
2x=z
x-2y+2z=1

Since 2x=z can be rewritten as 2x%2B0y-z=0, this means that the middle coefficient for 'y' of the 2nd row is 0. Let me know if you need help with any more parts of the problem.
