Answer:
5x - 11y - 6z
Step-by-step explanation:
Subtract common terms (terms with the same variable & same number of variables)
5x - 8y - 12z
- (+ 3y - 6z)
------------------
5x - 11y - 6z
Remember to distribute the negative sign to all terms within the second expression. Multiply -1 to all terms:
-1(3y) = - 3y
-1(-6z) = 6z
Combine the terms:
-8y - 3y = -11y
-12z + 6z = -6z
5x - 11y - 6z is your answer.
