Answer:
12p - 10q + 1
Explanation:
To find the answer, we add up numbers that have the same letter attached to them, since those are like terms.
Let's first add the numbers that have a p next to them.
3p + 9p = 12p
Are new expression is 12p - 4q - 6q + 1
Now let's add the numbers with q's next to them.
- 4q + -6q = -10q
Now we have the expression 12p - 10q + 1
There are no more numbers that have the same letter attached to them, so that is the simplest form it can be in.
12p - 10q + 1
