Divition is the answer 
Ex. a/b = a:b
        
             
        
        
        
I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.
 
        
        
        
Answer:
All you have to do is divide both sides by 2.5 to find your answer.
2.5x / 2.5 = 35 / 2.5
x = 14
The answer is X = 14.
I hope this helps!

P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
