133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$2y+y=399\\3y=399$

Dividing both sides by 3

$\frac{3y}{3}=\frac{399}{3}\\y=133$

133 adult tickets were sold.
