Answer:
168
Step-by-step explanation:
The first equation given as 
Where a is the number of adults and b is the number of students
<em>Since, the number of students are given as 82, we can plug 82 into b and then do algebra and solve for a (shown below):</em>
<em>
</em>
<em />
<em>Thus, </em><em>168 adult tickets were sold</em>
One solution: (0,-8) is the answer
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
