Break this problem into two subproblems by setting 
(t + 2) equal to 2.645751311 and -2.645751311.

Subproblem 1
t + 2 = 2.645751311

Simplifying
t + 2 = 2.645751311

Reorder the terms:
2 + t = 2.645751311

Solving
2 + t = 2.645751311

Solving for variable 't'.

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

Add '-2' to each side of the equation.
2 + -2 + t = 2.645751311 + -2

Combine like terms: 2 + -2 = 0
0 + t = 2.645751311 + -2
t = 2.645751311 + -2

Combine like terms: 2.645751311 + -2 = 0.645751311
t = 0.645751311

Simplifying
t = 0.645751311

Subproblem 2
t + 2 = -2.645751311

Simplifying
t + 2 = -2.645751311

Reorder the terms:
2 + t = -2.645751311

Solving
2 + t = -2.645751311

Solving for variable 't'.

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

Add '-2' to each side of the equation.
2 + -2 + t = -2.645751311 + -2

Combine like terms: 2 + -2 = 0
0 + t = -2.645751311 + -2
t = -2.645751311 + -2

Combine like terms: -2.645751311 + -2 = -4.645751311
t = -4.645751311

Simplifying
t = -4.645751311

Solution
The solution to the problem is based on the solutions
from the subproblems.
t = {0.645751311, -4.645751311}
