Answer:

-25x + 20

Step-by-step explanation:

I am going to assume by the lack of instructions, you wanted this simplified. We need to start by combining the -7 into the two terms in the paranthesis:

27 -4x -7 -21x

We can now combine like terms to simplify:

-25x + 20

27-4x+-7(1+3x)

27 - 4x - 7(1+3x)

27 - 4x - 7 - 21x

-25x + 20
