Answer:
3. 314 student and 226 adult
4. x = 6.5, y = -0.5
Step-by-step explanation:
3. First we will take our information and make a system of equations:
is the number of adult tickets sold and
is the number of student tickets sold.
From the second equation we can rearange it to be:
Then we can plug in our new value of to our first equation
We can then find by plugging in s to our second equation
4. It is mostly solved already. We can take the value of y from the first equation and plug it into the second to get:
Then plug our value of x into the first equation to get:
