[AI-generated answer — Bot GPT 3.5]

To solve for x, we need to combine like terms and isolate the variable x on one side of the equation.

First, we combine the like terms on the left side of the equation:

9x + 9x - 21 = 33
(9x + 9x) - 21 = 33
18x - 21 = 33

Next, we isolate the variable x by moving the constant term to the other side of the equation:

18x - 21 + 21 = 33 + 21
18x = 54

Lastly, we solve for x by dividing both sides of the equation by the coefficient of x:

18x/18 = 54/18
x = 3

Hence, the solution to the equation 9x + 9x - 21 = 33 is x = 3.
