Answer:
15x + 15
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables. Set the equation so that the terms are grouped:
6x + 9x + 6 + 9
Combine like terms:
(6x + 9x) = 15x
(6 + 9) = 15
15x + 15 is your answer.

In this question, you would be simplifying.
Simplify:
(-x³- x) + (6x² + 6x - 7)
-x³- x + 6x² + 6x - 7
-x³ + 6x² + 5x - 7
You can't simplify any further, so your answer would be:
-x³ + 6x² + 5x - 7
Answer:
-x^3 + 6x^2 + 5x - 7
