Subproblem 1
Set the factor '(39 + -1t)' equal to zero and attempt to solve:

Simplifying
39 + -1t = 0

Solving
39 + -1t = 0

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

Add '-39' to each side of the equation.
39 + -39 + -1t = 0 + -39

Combine like terms: 39 + -39 = 0
0 + -1t = 0 + -39
-1t = 0 + -39

Combine like terms: 0 + -39 = -39
-1t = -39

Divide each side by '-1'.
t = 39

Simplifying
t = 39
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 = {39, -1}
