To solve for this problem, we need to combine like-terms. Let's list our current variables: 2x - 2y - 5y + 5z - 2x - y + 3z; now, we need to list like-terms together and simplify. 2x - 2x; 0 2y - y; -3y 5z + 3z; 8z
Now, let's put this into an expression; -3y + 8z.
From our answer choices in the image above, the last option "D.) -3y + 8z" is the correct answer.
