Your picture has several issues.

x is not defined. It appears to be the number of apartments rented.
R(x) is defined two different ways. The first way, it looks like it is the revenue from a single apartment. The second way, it looks like it is the revenue from the entire apartment complex.
The derivative is in error. It should be -20x +2000. In any event, this is not the derivative you want. You're not trying to maximize revenue; you're trying to maximize profit.
It might be useful to write an equation for profit: P(x) = R(x) -200x = -10x² +1800x. Then when you go to maximize it, your derivative will be P'(x) = 0 = -20x +1800 ⇒ x = 90.

Your answer is correct, but the path you followed to get there has a few potholes.

Answer:

Step-by-step explanation:

6x + 18 = 12x

=> 18 = 12x - 6x

=> 18 = 6x

$= > x = \frac{18}{6}$
