Answer:
10x + 8
Step-by-step explanation:
Combine like terms. Like terms are terms with the same & same amount of variables.
In this case, order the terms based on their variables:
10x + 12y - 12y + 8
Note that there are two terms with one y. Combine the terms:
10x + (12y - 12y) + 8
10x + 0 + 8
10x + 8
10x + 8 is your answer.
