1 + 18 -7n=-9
19 - 7n=-9
Subtract 19 from both sides.
-7n=-28
Dide both sides by 7.
n=4
**Sorry, I put the wrong answer the first time. I thought it was a positive 9. My bad** :0)

you have to get n by itself, but I wont do it for you, i show you what to do.
1. First get rid of the 1 so subtract from both sides
1+ 18-7n = -9
-1 -1
2. Take the result and subtract 18
3. last of all, take the result and divide by -7
See, Easy!

18 - 7n = -9 - 1
-7n = -9 -1 -18
-7n = -28
n = -28 / -7
n = 4

n=4
1+18 =19
7(4) = 28
19 - 28= -9
