1. (3 * 6) + (3 * x) = 24

2. 18 + 3 * x = 24

3. 6 + x = 8

Step-by-step explanation:

We have the equation which is:

3 * (6 + x) = 24

The order of the solution would be as follows:

First step:

(3 * 6) + (3 * x) = 24

Second step:

18 + 3 * x = 24

Third step:

6 + x = 8

The rest of the steps are wrong, and have nothing to do with solving the equation.
