(2n-6n+5n+2)+(7n+2n-2n)=

Solution for (2n-6n+5n+2)+(7n+2n-2n)= equation:

Simplifying
(2n + -6n + 5n + 2) + (7n + 2n + -2n) = 0

Reorder the terms:
(2 + 2n + -6n + 5n) + (7n + 2n + -2n) = 0

Combine like terms: 2n + -6n = -4n
(2 + -4n + 5n) + (7n + 2n + -2n) = 0

Combine like terms: -4n + 5n = 1n
(2 + 1n) + (7n + 2n + -2n) = 0

Remove parenthesis around (2 + 1n)
2 + 1n + (7n + 2n + -2n) = 0

Combine like terms: 7n + 2n = 9n
2 + 1n + (9n + -2n) = 0

Combine like terms: 9n + -2n = 7n
2 + 1n + (7n) = 0
2 + 1n + (7n) = 0

Combine like terms: 1n + (7n) = 8n
2 + 8n = 0

Solving
2 + 8n = 0

Solving for variable 'n'.

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

Add '-2' to each side of the equation.
2 + -2 + 8n = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 8n = 0 + -2
8n = 0 + -2

Combine like terms: 0 + -2 = -2
8n = -2

Divide each side by '8'.
n = -0.25

Simplifying
n = -0.25
