Step 1:
Assume the number of adult tickets purchased is x and the number of student tickets purchased is y.
From the given data, we can write the following equations;
, take this as equation 1.
Since 8 tickets were purchased,
, take this as equation 2.
Step 2:
We rearrange equation 2 so we can substitute in equation 1.
, take this as equation 3.
By substituting equation 3 in equation 1, we get
Step 3:
Substituting this value of x in any of the previous equations we will get y's value.
Here this value of y is substituted in equation 2.
So we have x = 5 and y = 3. So there were 5 adult tickets and 3 student tickets.
