Answer:To solve for z in the equation 93 = 9z + 21, we can follow these steps:

Step 1: Subtract 21 from both sides of the equation:

93 - 21 = 9z + 21 - 21

Simplifying:

72 = 9z

Step 2: Divide both sides of the equation by 9:

(72) / 9 = (9z) / 9

Simplifying:

8 = z

Therefore, the solution for z in the equation 93 = 9z + 21 is z = 8.

In summary, to solve for z in the equation 93 = 9z + 21, we subtract 21 from both sides and then divide both sides by 9, which gives us the solution z = 8.
