Answer:
Correct option: C -> 2
Step-by-step explanation:
The first equation is:
And the second equation is:
From the second equation, we have:
Using this value of y in the first equation, we have:
Calculating the discriminant Delta, we have:
We have 
, so we have two real values for x, therefore we have two solutions for this system.
Correct option: C.
(If the system of equation is actually:
We would have:
We also have , so we have two solutions for this system.
Correct option: C.)

8 halls would be required to accommodate 520 people in the hall.
As we know that a hall can accommodate 65 people.
To determine the number of hall required for 520 people,
first we need to find that how many halls would be required for one person,
So, we will divide the 1 by 6 to find :
The number of one person accommodate = 1/65 Hall
Then, 520 people required to accommodate = 1/65 × 520
= 8 Halls.
