Question

Use Cramer's rule to solve the system of equations, if possible. (If the system is inconsistent, enter INCONSISTENT. If the system is dependent, enter DEPENDENT.)
x + y + 2z = 8
x + 2y + z = 10
2x + y + z = 10

Answer 1

Do you have to use Cramer's rule?

If you follow the steps, you should get
x = 3
y = 3
z = 1

for this system of equations
