If two adults and three children go to the movies, it costs $31.50. if one adult and five children go to the movies, it costs $35.00. what is the cost of one adult movie ticket? $5.50 $6.50 $7.50

The kids is 5.50 adult is 7..50

Step-by-step explanation:

we create an equation

2x + 3y =31.50

and

1x + 5y=35.00

1x is just x so we subtract 5y from both sides

x= 35.00-5y

fill x with 35.00-5y

2(35.00 - 5y) + 3y = 31.50

70.00 - 10y +3y = 31.50

-10y + 3y = -38.50

-7y=-38.50

-7y/-7= -38.50/-7

y=5.50
