For carson family,
2x + 3y = 192
For davis family,
x + 4y = 148
( x + 4y = 148 ) * 2
2x + 8y = 296
2x + 8y = 296
2x + 3y = 192
Subtract last equation from previous equation
5y = (296-192)
5y = 104
y = 20.8 dollars for one youth ticket
x = 148 - 83.2
x = 64.8 dollars for one adult ticket
2x + 3y = 192
