Question

An equation is shown:
-np - 3 = 7(c-4)
Which of the following solves for n?

Answer 1

Explanation:

To solve the equation -np - 3 = 7(c - 4) for n, we need to isolate the variable n on one side of the equation. Let's go through the steps:

Distribute the 7 on the right side:

-np - 3 = 7c - 28

Move the -3 term to the right side by adding 3 to both sides:

-np = 7c - 28 + 3

-np = 7c - 25

Divide both sides of the equation by -p to isolate n:

n = (7c - 25) / -p

Therefore, the expression that solves for n is n = (7c - 25) / -p.
