3.(-9x + 1)-(-7x + 8)

-20x-5

Step-by-step explanation:

you have to first distribute,

3(-9x+1)-1(-7x+8)

-27x+3-1(-7x+8)

-27x+3-1(-7x+8)

-27x+3+7x-8

now you have to subtract the numbers.

-27x+3+7x-8

-27x-5+7x

now you have to combine like terms,

-27x-5+7x

-20x-5

and thats how you get your answer.

hope this helps you.      :)
