Atotal of 439 tickets were sold for the school play. they were either adult tickets or student tickets. there were 61 fewer students tickets sold than adults tickets. how many adult tickets were sold ?

250 adult tickets were sold.

Step-by-step explanation:

Let x represent the number of adult tickets sold for the school play.

Let y represent the number of student tickets sold for the school play.

A total of 439 tickets were sold for the school play. This means that

x + y = 439 - - - - - - - - - - - - - - 1

There were 61 fewer students tickets sold than adults tickets. This means that

x - 61 = y

Substituting y = x - 61 into equation 1, it becomes

x + x - 61 = 439

2x - 61 = 439

2x = 439 + 61

2x = 500

x = 500/2 = 250

y = x - 61 = 250 - 61

y = 189

x equals 1
