What is the answer of 6=1-2n+5

6 = 1 - 2n + 5

5 = - 2n + 5

0 = - 2n

n=0

IF you are solving for N, then I think this is the way to do it.

6=1-2n+5

combine light terms:

6 = (1+5) - 2n

6=-2n+6

now try to get N by itself so you subtract 6 on both side:

6=-2n+6

-6 - 6

now you have 0=-2n or - 2n=0

now divide both sides by - 2

-2n/-2 = 0/-2

so it's a no solution. but if it doesn't give you that option, then n=0
