Question

1. - 3p + 6p
2. 6 - 3 + 6 - 2b
3. 7x - x
4. 7p - 10p
5. - 10v + 6v
6. - 9r + 10
7. q + 5r - 9r
8. 1 - 3v + 10

Explanation:

Step1: Combine like - terms for each expression

1. For $-3p + 6p$, we have $(-3 + 6)p=3p$.
2. For $6-3 + 6-2b$, first combine the constant terms: $(6 - 3+6)-2b = 9 - 2b$.
3. For $7x - x$, we have $(7 - 1)x = 6x$.
4. For $7p-10p$, we have $(7 - 10)p=-3p$.
5. For $-10v + 6v$, we have $(-10 + 6)v=-4v$.
6. $-9r + 10$ is already in simplest form as there are no like - terms to combine.
7. For $q + 5r-9r$, combine the $r$ terms: $q+(5 - 9)r=q - 4r$.
8. For $1-3v + 10$, combine the constant terms: $(1 + 10)-3v=11-3v$.

Answer:

1. $3p$
2. $9 - 2b$
3. $6x$
4. $-3p$
5. $-4v$
6. $-9r + 10$
7. $q - 4r$
8. $11-3v$
