Provide an appropriate response.Without solving the following system of equations, tell what the solution is. Explain your answer. 6x + 2y + 5z = -518x + 6y + 15z = -136x + 12y + 30z = -5
What will be an ideal response?
There are no solutions since the three equations represent three parallel planes. (Explanations will vary.)
