Simple, I used reversal.
Here the question
"A bus was traveling with 48 passengers, after some while the bus reached a stop and x passengers got off and 3 passengers got on abroad. When the bus reached another stop, half the passengers got off and 4 got on. There are now 22 passengers. Solve x."
And how to solve ? Start from the last.
(There are now 22 passengers) The last passengers were 22
(4 got on) 22-4 = 18
(half the passengers got off) 18 x 2 = 36
(3 passengers got on abroad) 36-3 = 33
(x passengers got off ) The passengers were 33 + X
(A bus was traveling with 48 passengers) 33 + X = 48 ===> 48 - 33 = 15
