Answer 1

To simplify the expression \( 911z - 411z \), we can combine like terms. Both terms contain the variable \( z \).

Here's how it works step by step:

\[ 911z - 411z = (911 - 411)z \]

Now, we subtract 411 from 911:

\[ 911 - 411 = 500 \]

So, we can rewrite the expression as:

\[ 500z \]

Thus, the simplified expression is:

\[ \boxed{500z} \]
