# Finding Both Minimum And Maximum

**Algebra**Level 5

\[\large\begin{cases} x+y+z=4\\ x^2+y^2+z^2=6\end{cases}\]

If \(x,y\) and \(z\) are reals numbers that satisfy the system of equations above, find the sum of the maximum and the minimum value of \(A= x^6+y^6+z^6\).

Round your answer to the nearest integer.
