Break this problem into two subproblems by setting 
(t + 1) equal to 6.08276253 and -6.08276253.

Subproblem 1
t + 1 = 6.08276253

Simplifying
t + 1 = 6.08276253

Reorder the terms:
1 + t = 6.08276253

Solving
1 + t = 6.08276253

Solving for variable 't'.

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

Add '-1' to each side of the equation.
1 + -1 + t = 6.08276253 + -1

Combine like terms: 1 + -1 = 0
0 + t = 6.08276253 + -1
t = 6.08276253 + -1

Combine like terms: 6.08276253 + -1 = 5.08276253
t = 5.08276253

Simplifying
t = 5.08276253

Subproblem 2
t + 1 = -6.08276253

Simplifying
t + 1 = -6.08276253

Reorder the terms:
1 + t = -6.08276253

Solving
1 + t = -6.08276253

Solving for variable 't'.

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

Add '-1' to each side of the equation.
1 + -1 + t = -6.08276253 + -1

Combine like terms: 1 + -1 = 0
0 + t = -6.08276253 + -1
t = -6.08276253 + -1

Combine like terms: -6.08276253 + -1 = -7.08276253
t = -7.08276253

Simplifying
t = -7.08276253

Solution
The solution to the problem is based on the solutions
from the subproblems.
t = {5.08276253, -7.08276253}
