The correct process is to combine like terms, which are terms that have the same variable raised to the same power. Here, $2z^4$ and $5z^4$ are like terms, so we add them together to get $7z^4$. The terms $-11z$ and $-5$ do not have like terms to combine with, so they remain as they are. The final expression is $7z^4 - 11z - 5$.
