A total of 765 tickets were sold for the school play. They were either adults or students tickets. There were 65 more student tickets sold than adult tickets. How many adult tickets were sold?

350 adult tickets

Step-by-step explanation:

(omg I remember this question!)

student tickets : a + 65

the equation for the prob:

765 = a + (a + 65)

solve:

combine 'like terms'

765 = a + a + 65

765 = 2a + 65

- 65         - 65

700 = 2a

700/2 = 2a/2

(700/2 = 350)

(the "2" in 2a is cancelled out by the other 2)

350 = a
