n=(n+2)+(n+4)

Solution for n=(n+2)+(n+4) equation:

Simplifying
n = (n + 2) + (n + 4)

Reorder the terms:
n = (2 + n) + (n + 4)

Remove parenthesis around (2 + n)
n = 2 + n + (n + 4)

Reorder the terms:
n = 2 + n + (4 + n)

Remove parenthesis around (4 + n)
n = 2 + n + 4 + n

Reorder the terms:
n = 2 + 4 + n + n

Combine like terms: 2 + 4 = 6
n = 6 + n + n

Combine like terms: n + n = 2n
n = 6 + 2n

Solving
n = 6 + 2n

Solving for variable 'n'.

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

Add '-2n' to each side of the equation.
n + -2n = 6 + 2n + -2n

Combine like terms: n + -2n = -1n
-1n = 6 + 2n + -2n

Combine like terms: 2n + -2n = 0
-1n = 6 + 0
-1n = 6

Divide each side by '-1'.
n = -6

Simplifying
n = -6
