134 adult tickets were sold.
Step-by-step explanation:
Let,
Adult tickets = x
Student tickets = y
According to given statement;
x + y = 536 Eqn 1
As the number of students tickets are three times more, therefore
y = 3x Eqn 2
Putting value of y in Eqn 1;
[tex]x+3x=536\\4x=536\\Dividing\ both\ sides\ by\ 4\\\frac{4x}{4}=\frac{536}{4}\\ x=134[/tex]
134 adult tickets were sold.
