Expanding both sides of the equation, we get:
4z - 8 = 3z + 9
To isolate the variable z, we subtract 3z from both sides:
4z - 3z - 8 = 3z + 9 - 3z
Simplifying, we have:
z - 8 = 9
Adding 8 to both sides, we get:
z - 8 + 8 = 9 + 8
Simplifying, we have:
z = 17
Therefore, the solution is z = 17.
2(2z - 4) = 3(z + 3)

3(3x - 1) = 12
Expanding both sides of the equation, we get:
9x - 3 = 12
To isolate the variable x, we add 3 to both sides:
9x - 3 + 3 = 12 + 3
Simplifying, we have:
9x = 15
Dividing both sides by 9, we get:
9x/9 = 15/9
Simplifying, we have:
x = 5/3
Therefore, the solution is x = 5/3.
9x - 3 = 12
To isolate the variable x, we add 3 to both sides:
9x - 3 + 3 = 12 + 3
Simplifying, we have:
9x = 15
Dividing both sides by 9, we get:
9x/9 = 15/9
Simplifying, we have:
x = 5/3
Therefore, the solution is x = 5/3.
