An equation is shown:

−np − 6 = 3(c − 5)

Which of the following solves for n?

n = the quantity 3 times c minus 21 all over negative p
n = the quantity 3 times c minus 9 all over negative p
n = the quantity 3 times c minus 21 all over p
n = the quantity 3 times c minus 9 all over p

Answer:

Option 2

Step-by-step explanation:

Hello!

We can solve the equation for n by isolating the variable.

Solve for n:

  • -np - 6 = 3(c - 5)             Add 6 to both sides
  • -np = 3(c - 5) + 6             Divide both sides by p
  • -n = [tex]\frac{3(c - 5) + 6}{p}[/tex]                     Expand the parenthesis
  • -n = [tex]\frac{3c - 15 + 6}{p}[/tex]                      Combine Like terms
  • -n = [tex]\frac{3c - 9}{p}[/tex]                           Divide both sides by -1
  • n = [tex]-\frac{3c - 9}{p}[/tex]

The answer would be the second option: "n = the quantity 3 times c minus 9 all over negative p."
