The cost of the brother's ticket is $5.
Two simultaneous equations can be determined from the given question
x - y = 2 equation 1
x + y = 12 equation 2
Where:
x = price of Michael's ticket
y = price of younger brother's ticket
In order to determine the cost of the ticket for the brother, subtract equation 1 from 2
2y = 10
divide both sides of the equation by 2
y = 5
