Break this problem into two subproblems by setting 
(x + 6) equal to 6.92820323 and -6.92820323.

Subproblem 1
x + 6 = 6.92820323

Simplifying
x + 6 = 6.92820323

Reorder the terms:
6 + x = 6.92820323

Solving
6 + x = 6.92820323

Solving for variable 'x'.

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

Add '-6' to each side of the equation.
6 + -6 + x = 6.92820323 + -6

Combine like terms: 6 + -6 = 0
0 + x = 6.92820323 + -6
x = 6.92820323 + -6

Combine like terms: 6.92820323 + -6 = 0.92820323
x = 0.92820323

Simplifying
x = 0.92820323

Subproblem 2
x + 6 = -6.92820323

Simplifying
x + 6 = -6.92820323

Reorder the terms:
6 + x = -6.92820323

Solving
6 + x = -6.92820323

Solving for variable 'x'.

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

Add '-6' to each side of the equation.
6 + -6 + x = -6.92820323 + -6

Combine like terms: 6 + -6 = 0
0 + x = -6.92820323 + -6
x = -6.92820323 + -6

Combine like terms: -6.92820323 + -6 = -12.92820323
x = -12.92820323

Simplifying
x = -12.92820323

Solution
The solution to the problem is based on the solutions
from the subproblems.
x = {0.92820323, -12.92820323}
Solution
x = {0.92820323, -12.92820323}
