Provide an appropriate response.Without solving the following system of equations, tell what the solution is. Explain your answer. 4x - 3y - 3z = 38x - 6y - 6z = 4-16x + 12y + 12z = 6
What will be an ideal response?
There are no solutions since the three equations represent three parallel planes. (Explanations will vary.)
