Simplify the following expression Z-2z+4z+6

(1-2+4)z + 6

Z-2z+4z+6

Combine like terms
Z-2z= -1z
-1z+4z+6
-3z+6

To simplify the expression Z - 2z + 4z + 6, we need to combine like terms.

First, let's group together the terms that contain the variable z:

-2z + 4z

This simplifies to 2z, as the negative sign cancels out when adding a positive 4z.

Now, let's rewrite the expression with the simplified term:

Z + 2z + 6

Since there is no like term for Z, we leave it as it is.

Finally, the simplified expression is:

Z + 2z + 6
