-16z - 19 = -12z + 9

To solve the equation -16z - 19 = -12z + 9, you can begin by combining like terms.

First, subtract -12z from both sides of the equation:
-16z - 19 + 12z = -12z + 9 + 12z
This simplifies to:
-4z - 19 = 9

Next, add 19 to both sides of the equation:
-4z - 19 + 19 = 9 + 19
This simplifies to:
-4z = 28

Finally, divide both sides of the equation by -4 to solve for z:
-4z / -4 = 28 / -4
This simplifies to:
z = -7

Therefore, the solution to the equation is z = -7.
