Answer:

[tex] \boxed{\sf 3x + 10} [/tex]

Step-by-step explanation:

Simplify the following:

⇒-9 x + 12 x + 10

Grouping like terms:

⇒(12 x - 9 x) + 10

12 x - 9 x = 3 x:

⇒3 x + 10
3x+10 because you have to combine -9x and 12x which will give you 3x. Then the 10 can’t go to 3x because they aren’t like terms. So your answer is 3x+10.
