-40+2n=4n-8 (n+8)

Answer: n = 6

Step-by-step explanation:

The given equation is expressed as

-40+2n = 4n-8 (n+8)

We would open the parenthesis on the right hand side of the equation by multiplying each term inside the parenthesis by the term outside. It becomes

- 40 + 2n = - 4n - 64

We would make all terms containing n to be on the left hand side of the equation and the constant terms to be on the right side of the equation. It becomes

2n - 6n = - 64 + 40

- 4n = - 24

Dividing the left hand side and the right hand side of the equation by

- 4, it becomes

- 4n/-4 = - 24/-4

n = 6

-40 + 2n = 4n - 8 (n+8)

-40 + 2n = 4n - 8n - 64

-40 + 2n = - 4n - 64

2n = - 4n - 64 + 40

2n=-4n-24

2n+4n=-24

8n=-24

N = - 3

Answer is n equals - 3
