Subproblem 1
Set the factor '(11 + -2t)' equal to zero and attempt to solve:

Simplifying
11 + -2t = 0

Solving
11 + -2t = 0

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

Add '-11' to each side of the equation.
11 + -11 + -2t = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -2t = 0 + -11
-2t = 0 + -11

Combine like terms: 0 + -11 = -11
-2t = -11

Divide each side by '-2'.
t = 5.5

Simplifying
t = 5.5
Subproblem 2
Set the factor '(1 + t)' equal to zero and attempt to solve:

Simplifying
1 + t = 0

Solving
1 + t = 0

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 = 0 + -1

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

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

Simplifying
t = -1
Solution
t = {5.5, -1}
