9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
Could be anything! We'd have to know the final sum to figure out what "N" would be, like 5N +N = 24.
5n = 2n + 3n .
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
5m-5n+5m+5n When simplified: 10m
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
Tenth term of 5n + 1 = 5*10 + 1 = 51
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5n + 10 = 10 5n = 10 - 10 5n = 0 n = 0 taylor101119: well i thought it was 5*n+5*2=10 i thought n=1 but i'm pretty sure it's the one ontop^
5n - 10 = 0 5n - 10 (+10) = 0 (+10) 5n (/5) = 10 (/5) n = 2
3n+5n=8n
6n + 5n is 11n.
5n-25 = 10 5n = 10+25 5n = 35 n = 7
4 over 5n
