8n-n=3(1+4n)+3(1-n)

Solution for 8n-n=3(1+4n)+3(1-n) equation:

8n-n=3(1+4n)+3(1-n)

We move all terms to the left:

8n-n-(3(1+4n)+3(1-n))=0

We add all the numbers together, and all the variables

8n-n-(3(4n+1)+3(-1n+1))=0

We add all the numbers together, and all the variables

7n-(3(4n+1)+3(-1n+1))=0


We calculate terms in parentheses: -(3(4n+1)+3(-1n+1)), so:

3(4n+1)+3(-1n+1)

We multiply parentheses

12n-3n+3+3

We add all the numbers together, and all the variables

9n+6

Back to the equation:

-(9n+6)


We get rid of parentheses

7n-9n-6=0

We add all the numbers together, and all the variables

-2n-6=0

We move all terms containing n to the left, all other terms to the right

-2n=6

n=6/-2

n=-3
