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 - 7y + 4z = -18
-2x + 14y - 8z = 20
-5x - y - 2z = 15
