Create formulas!

x=number of adult tickets

y=number of student tickets

x+y=644  total sold

56+y=x    student was 56 less than adult

Perform substitution

(56+y)+y=644

56+2y=644

2y=588

y=294

Substitute y into the formula we created

x+294=644

x=350

350 adult tickets were sold.

Answer:

Step-by-step explanation:

Let x be the number of adult tickets.

Number of student tickets = 56 fewer than adult tickets

                                            = x - 56

Total tickets  = 644

x + (x - 56) = 644

x + x - 56 = 644

2x - 56 = 644

Add 56 to both sides

2x - 56 + 56 = 644 + 56

2x = 700

Divide both sides by 2

2x/2 = 700/2

x = 350

350 adult tickets were sold
