Simplify 911z − 411z.

Answer 1

To simplify the expression \( 911z - 411z \), you can combine the like terms:

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

Calculating \( 911 - 411 \):

\[ 911 - 411 = 500 \]

Now substituting back, we have:

\[ 911z - 411z = 500z \]

So, the simplified expression is:

\[ \boxed{500z} \]
