Answer 1

Answer:

(B) -3x - 4

Step-by-step 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

Answer 2

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
