Answer:

Pudge sold 8 tickets, Christi sold 19

tickets, Ace sold 38 tickets

Explanation:

x = Pudge

3x - 5 Christi

2(3x-5) = Ace

Let x, 3x - 5 and 2(3x-5) be the tickets

x + (3x- 5) +2(3x - 5) = 65

Combine like terms

x+ (3x - 5) + 6x - 10 = 65

4x -5+6x - 10 = 65

10x - 5-10 = 65

Transpose -5 and -10 and change their

signs

10x = 65 +5+ 10

Add

10x = 80

Divide both sides by 10

10x/10x = 80/10

x =8

Pudge sold 8 tickets.

Evaluate x as 8

3x-5

3(8)-5

24-5 19

Christi sold 19 tickets.

2(3x-5)

2(3(3)- 5)

2(24- 5)

2(19)= 38

Ace sold 38 tickets.

Checking:

x+ (3x - 5) +2(3x - 5) = 65

8+(3(8)-5) +2(3(8) - 5) = 65

8 +19 +38 = 65

65 =65
