Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:
![\left \{ {{x+y=32} \atop {3x+27y=408}} \right. \ =\ \textgreater \ \ \left \{ {{x=19 (cars)} \atop {y=13(buses)}} \right.](https://tex.z-dn.net/?f=%20%5Cleft%20%5C%7B%20%7B%7Bx%2By%3D32%7D%20%5Catop%20%7B3x%2B27y%3D408%7D%7D%20%5Cright.%20%5C%20%3D%5C%20%5Ctextgreater%20%5C%20%20%5C%20%20%5Cleft%20%5C%7B%20%7B%7Bx%3D19%20%28cars%29%7D%20%5Catop%20%7By%3D13%28buses%29%7D%7D%20%5Cright.%20)
