<h2>
Answer:</h2><h3>False</h3>
<h2>
Step-by-step explanation:</h2>
In this problem, we have the following System of Three Equations in Three Variables, so our goal is to determine whether
is the solution to this system, that is, the ordered triple
where three planes intersect.
The easier way to find the answer is to plug in the x, y and z values in the equations and figure out whether the equations satisfy the solutions. Then:

STOP HERE! Since the x, y an z values doesn't satisfy the second equation, the
is not the solution to the system of equations.
Letter A is right
Explanation: best of luck
