Question

12z = 5z - 18 - 2z решить)

Answer 1

Ответ:

12z=3z-18

12z-3z=-18

9z=-18

z=-2

Answer 2

To solve the equation, we need to isolate the variable z on one side of the equation. Let's go step by step to find the solution:

1. Combine like terms on the right side: 12z = 5z - 18 - 2z

2. Combine the z terms on the right side: 12z = 3z - 18

3. Move the 3z term to the left side by subtracting 3z from both sides: 12z - 3z = -18

4. Simplify the left side: 9z = -18

5. Finally, isolate z by dividing both sides by 9: z = -18 / 9

6. Compute the value of z: z = -2

So, the solution to the equation is z = -2.
