Can someone explain what's n+1-3n=-5+n+1-2

N+1-3n=5+n+1-2

Simplify it

-2n+1 = n+4

Add 2n to both sides

1 = 3n+4

Subtract 4 from both sides

-3 = 3n

Divide by 3

n = - 1

N + 1 - 3n = - 5 + n + 1 - 2

Combine like terms:

n - 3n = - 2n

-2n + 1 = - 5 + n + 1 - 2

Combine like terms:

-5 + 1 - 2 = - 6

-2n + 1 = n - 6

Subtract 'n' to both sides:

-3n + 1 = - 6

Subtract 1 to both sides:

-3n = - 7

Divide - 3 to both sides:

n = 2 1/3 or 7/3
