Here is the equation:


-(8x+4)+5x

The first thing you need to do is distribute the negative for the equation in the parentheses.


(8x+4) \\ \\ 8x \rightarrow -8x \\ +4 \rightarrow -4

Here is your new equation:


-8x-4+5x

Now you need to combine like terms. You have -8x and 5x. You can just add -8 and 5 and then add the x.


-8x+5x \\ \\ -8+5 = -3 \\ -3 \rightarrow -3x

Here is your new equation:


-3x-4

Your answer is the 2nd choice, -3x - 4

If you have any questions, feel free to ask in the comments! :)

Answer:

(B) -3x - 4

Explanation:

First, note that the equation is:

-1(8x + 4) + 5x

Distribute the -1 to all terms within the parenthesis

-1(8x) = -8x

-1(4) = -4

-8x + 5x - 4

Simplify. Combine like terms

(5x - 8x) - 4

-3x - 4

(B) - 3x - 4 is your answer
