Question

- 8n - 8 = -72
I don’t know how to do this

Answer 1

Start by turning everything positive! 8n + 8 = 72.
Then, having the 8 as a positive number, subtract it from the left side. 8n = 64
In our final step, we divide 64 by 8 to find what n is, n= 8
To check your work you can plug it back into the original equation, be sure that both sides equal each other!

Answer 2

n=8

Explanation:

Add 8 to both sides of the equals sign, then bring down -8n, add -72+8, You'll get -64, lastly you divide -64 and -8, and you'll get your answer
