Mnx+mny-mnz nx+ny-nc ad+ac mnx+mny+mnz ab-ac

1. To simplify the expression mnx + mny - mnz, we can factor out the common term "mn", which gives us:

mn(x + y - z)

2. The expression nx + ny - nc does not have any common factors that can be simplified further.

3. Similarly, the expression ad + ac does not have any common factors that can be simplified further.

4. For the expression mnx + mny + mnz, we can factor out "mn" to get:

mn(x + y + z)

5. Finally, for the expression ab - ac, there are no common factors to simplify further.
