We solve the system by applying the following steps: 1) Write two of the variables in terms of the third variable. For this case we write x, y in terms of z. 2) Substitute the expressions in the first equation since it relates all the variables. 3) Clear z. 4) with the value of z, find x, y Answer: A. x = 0, y = 1, z = 2 See attached image.
