Answer:

z = 0

Step-by-step explanation:

Step 1: Write equation

9z - 5 - 4z = -5

Step 2: Solve for z

  1. Combine like terms: 5z - 5 = -5
  2. Add 5 to both sides: 5z = 0
  3. Divide both sides by 5: z = 0

Step 3: Check

Plug in x to verify it's a solution.

9(0) - 5 - 4(0) = -5

0 - 5 - 0 = -5

-5 = -5

Answer:

z=0

Step-by-step explanation:

First, let's combine like terms (9z and -4z). When we add these two values, we get 5z. This leaves the left side to be 5z-5 and that is equal to -5. To get z by itself, we have to add 5 on both sides. This equals 5z=0. Then, we divide by 5 on both sides since the inverse operation of multiplication is division. This leaves z=0.
