Combine like terms: 3x + 11y - 10z - 5y - 4z + 12x
Ivan
Hello there!

First, let's categorize our monomials with the proper variables.

3x + 12x
11y - 5y
-10z -4z

Now, we can make these into simpler terms by adding/subtracting the sectioned variables.

3x + 12x = 15x
11y - 5y = 6y
-10z - 4z = -14z

Now let's place our results into an expression as a final answer.

15x + 6y - 14z is your final expression.

I hope this helps!
