**Let x = the price of an adult ticket**

**Let y = the price of an child ticket**

**2x + 12y = 94**

**9x + 4y = 73 Multiply this equation by -3 and add it to the first equation.**

**2x + 12y = 94**

**-27x -12y = -219**

**-25x = -125**

**x = 5 adult tickets**

**2(5) + 12y = 94**

**10 + 12y = 94**

**12y = 84**

**y = 7 child tickets**
