Solve the system of equations. Remember: systems with one solution will have an answer in the form of an ordered triplet.
Example: (3, -4, 10)
For systems with infinite solutions or no solutions, write the words ‘infinite solutions’ or ‘no solutions’.
x + 2y -z = 2
2x - 7y + 5z = 3
-4x + y + 2z = 4
