Answer:

A. -9n + 20

Step-by-step explanation:

First, distribute -5 to all terms within the parenthesis:

-5(2n - 4) + n

(-5 * 2n) + (-5 * -4) + n

-10n + 20 + n

Simplify. Combine like terms:

(-10n + n) + 20

(-9n) + 20

A. -9n + 20 is your answer.

Natasha2012 [34]

Answer:

If problem is "-|2x+3|+8=12"

then there is (<em>no solution.)</em>

Step-by-step explanation:

Let's solve your equation step-by-step.

−|2x+3|+8=12

Step 1: Add -8 to both sides.

−|2x+3|+8+−8=12+−8

−|2x+3|=4

Step 2: Divide both sides by -1.

−|2x+3|=4

   -1       -1

|2x+3|=−4

Step 3: Solve Absolute Value.

|2x+3|=−4

No solutions Because absolute value is less than 0.
