2n+n+0.1+2n+n+0.1=n

Solution for 2n+n+0.1+2n+n+0.1=n equation:

Simplifying
2n + n + 0.1 + 2n + n + 0.1 = n

Reorder the terms:
0.1 + 0.1 + 2n + n + 2n + n = n

Combine like terms: 0.1 + 0.1 = 0.2
0.2 + 2n + n + 2n + n = n

Combine like terms: 2n + n = 3n
0.2 + 3n + 2n + n = n

Combine like terms: 3n + 2n = 5n
0.2 + 5n + n = n

Combine like terms: 5n + n = 6n
0.2 + 6n = n

Solving
0.2 + 6n = n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1n' to each side of the equation.
0.2 + 6n + -1n = n + -1n

Combine like terms: 6n + -1n = 5n
0.2 + 5n = n + -1n

Combine like terms: n + -1n = 0
0.2 + 5n = 0

Add '-0.2' to each side of the equation.
0.2 + -0.2 + 5n = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + 5n = 0 + -0.2
5n = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
5n = -0.2

Divide each side by '5'.
n = -0.04

Simplifying
n = -0.04
