Question

15-3n=n-1

Answer 1

Isolate the variable.

Answer 2

move all the constants to one side, and all the variables to the other.

Answer 3

Combine like terms, and divide.

Answer 4

a-bn=n=c
a-c=n+bn
a-c=(1+b)n
n=(a-c)/(1+b)

Answer 5

I did it. I subtracted -1n from -3n and from 1n. then I got 15-4n=-1. Then I added 4n to -4n and to -1. Then I got 15=3n, and then I divided 3n by 3 and 15 by 3, and then I got n=5 but that isn't right.

Answer 6

Should be, subtracted n, not -n

Answer 7

Or, added -n.

Answer 8

On the very beginning part?

Answer 9

yes.

Answer 10

I'm very bad at math.

Answer 11

subtract both sides by only n

Answer 12

if you subtract by -n, it actually means you are adding by n. Here's why
-(-n)=-1*(-1*n)=1n=n
