5n+2 or 5n-2. I'll assume 10n 10,20,30,40,50
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 .

first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
It is 1 + 5N.

5m-5n+5m+5n When simplified: 10m
it is 8.
5n+2 or 5n-2. I'll assume 10n 10,20,30,40,50

4n + 1 = 12 + 5n First, let's get all n terms on one side and all non-n terms on the other side. Start off by subtracting 4n from each side. 1 = 12 + n Now subtract 12 from each side. -11 = n

3n+5n=8n
