Jen butler has been pricing speed-pass train fares for a round trip to New York three adults and four children must pay $118 two adults and three children must pay 84$ find the price of the adults ticket and the price of a child’s ticket

Respuesta :

Answer:

Adult’s ticket = $ 18

Child’s ticket = $ 16

Step-by-step explanation:

Adults: x

Children: y

(3x + 4y = 118) * (2) = 6x + 8y = 236

(2x + 3y = 84) * (-3) = -6x - 9y = -252

Add both equations:

-y = - 16

y = 16

3x + 4(16) = 118

3X + 64 = 118

3X = 118 - 64

X = 54/3=18
