Question

10n+ 20n - 80 = 0
What’s the answer

Answer 1

10n + 20n - 80=0
30n-80=0
30n=80

Devide by 30 on each side so “n” can stay alone

n = 30
-
80
Reduce by 10 to simpler form

n = 3
-
8
Thats the ans

Answer 2

n=8/3

Explanation:

combine like terms: 30n-80=0

add 80 to both sides: 30n=80

divide by 30: n=80/30

simplify: n=8/3
