Subproblem 1
Set the factor '(3 + z)' equal to zero and attempt to solve:

Simplifying
3 + z = 0

Solving
3 + z = 0

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

Add '-3' to each side of the equation.
3 + -3 + z = 0 + -3

Combine like terms: 3 + -3 = 0
0 + z = 0 + -3
z = 0 + -3

Combine like terms: 0 + -3 = -3
z = -3

Simplifying
z = -3
Subproblem 2
Set the factor '(1 + 10z)' equal to zero and attempt to solve:

Simplifying
1 + 10z = 0

Solving
1 + 10z = 0

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

Add '-1' to each side of the equation.
1 + -1 + 10z = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 10z = 0 + -1
10z = 0 + -1

Combine like terms: 0 + -1 = -1
10z = -1

Divide each side by '10'.
z = -0.1

Simplifying
z = -0.1
Solution
z = {-3, -0.1}
