Answer:
he should share 11 tickets
Step-by-step explanation:
Since Alan has more tickets he transfers a quantity "x" to his brother.
Now Alan has = 41 stickers - "x" stickers that he borrowed
And his brother has now = 19 stickers + "x" stickers that he received from Alan
Since now they have the same number of tickets
Tickets that has Alan = Tickets that has this brother
41 - x = 19 + x
summing x in both sides
41 - x + x = 19 + x + x
41 - 0 = 19 + 2*x
subtracting 19
41 - 19 = 2*x
dividing by 2
22 / 2 = 2*x /2
x = 22/2 = 11
so both will have 30 tickets
