Answer:
10a-4b+6
Step-by-step explanation:
To simplify, we need to combine like terms.
That means terms with the same variable, or just numerical values without a variable can be added together.
9a-4b+a+6
We can combine 9a and a together.
10a-4b+6
None of the terms can still be combined, so that is in simplest form.
