Solve the system of linear equations and check any solutions algebraically.

You may use the substitution method to solve the system, hence, you need to use the first equation to write x in terms of y and z, such that:



You may now replace  for x in equation , such that:


You may use the substitution method to solve the system, hence, you need to use the first equation to write x in terms of y and z, such that:



You may now replace  for x in equation , such that:



You may use the third equation, , along with   equation, such that:



You may replace 3 for z in equation



You may replace 3 for z and for y in equation



Hence, evaluating the solution to the given system, yields
