5n+20n=5(n+20)
5n+20n=5(n+20)
27n=100+5n ****************** 25n = 5n + 100, not 27n
20n = 100
n = 5

5n+2n=5(n+20)
7n=5(n+20)
7n=100+5n
7n-5n=(5n-5n)+100
2n=(5n-5n)+100
5n-5n=0
2n=100
n=100/2
you can do long division to simplify
2 divided by 100=50
n=50

5n+20n=5(n+20)
5n+20n=5(n+20)
27n=100+5n
27n/5=100+5n/5
?=20+n
I do not know where to go from here or how to make sense of this

First of all, where did you get 27n from? Isn't 5 + 20 = 25?

5n + 20n = 5(n + 20)

25n = 5n + 100

25n - 5n = 100

20n = 100

n+=+100%2F20, or highlight_green%285%29

You can check to see if it makes sense!!
