3z + 9 = 0
Reorder the terms:
9 + 3z = 0
Solving
9 + 3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 3z = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 3z = 0 + -9
3z = 0 + -9
Combine like terms: 0 + -9 = -9
3z = -9
Divide each side by '3'.
z = -3
Simplifying
z = -3

Answer:
-2, 1, 4.
Step-by-step explanation:
The given equation is
It can be written as a system of equations.
Plot the graph of these equation on a coordinate plane as shown below.
From the graph it is clear that the graph of both curves intersect each other at (-2,4), (1,-5) and (4,40).
The x-coordinates of intersection points are -2,1 and 4. It means, the given equation is true for -2,1 and 4.
Therefore, the zeroes of given equation are -2,1 and 4.
