Note: I just noticed that you only have one negative sign. If you mean to put -9, change the sign to positive. If not, leave the answer.
Note the equal sign. what you do to one side, you do to the other. Isolate the x. First, multiply 3 to both sides
-x/3(3) = 9(3)
-x = 9(3)
-x = 27
Next, to isolate the x, divide -1 from both sides
-x/-1 = 27/-1
x = 27/-1
x = -27
-27 is your answer for x.
hope this helps

Answer:
a) 
b) 
Step-by-step explanation:
For this case we can use a linear model to solve the problem. 
s) Create an equation to express the increase on the price tickets and the number of seats sold
 number of seats, if w analyze the info given the number of seats after increase the price is given by
 number of seats, if w analyze the info given the number of seats after increase the price is given by  .
.
And let P the price for the ticket. So after the increase in ticket price the expression for the increase is P-200. 
We have an additional info, for each increase of $3 the number of setas decrease 1. And the equation that gives to us the price change in terms of the increase of price is:

So then our linear equation is given by:

b) Over a certain period, the number of seats sold for this flight ranged between 90 and 115. What was the corresponding range of ticket prices?
So for this case we just need to replace the limits into the linear equation and see what we got:


So the corresponding range of ticket prices is:

 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
Add 3x^2 and 5x^2 now it = 8x^2
Add -8x and -4x = -12x
look at your answer choices the only one that has 8x^2-12x is A
