    28,32] = 224 (the minimum number that basically meets the conditions of this question) is more than 400 sheets, so 224 2 gets 448 sheets, that is, the total number of stamps for two people.

    448 32/32 (19-6) = 182 (sheets).The number of stamps after getting a stamp from Xiao Ming to Xiao Lin.

    448 17/28 = 272 (sheets).Get the number of stamps after Tom received a stamp.

    The difference between these two numbers is 2 a (one is given and the other is received), so we can divide the difference between 272 and 182 by 2 to get the number of 1 a, which is a = (272-182) 2 = 45

    With 272-a = 272-45 = 227 (sheets), that is, Xiao Ming's original number of stamps.

    Finally, 448-227 = 221 (sheets) is used, which is the original number of stamps of Kobayashi.

    The above process is a bit complicated, sorry.

    Set Xiao Ming's stamp x, Xiao Lin Y, there are.

    x-a) (y+a)=1-6 19 (1)y-6) (x+a)=1-6 17 (2)400 merge the first two equations, and denote x y by a respectively.

    x=(908/180)a (5)

    y=(884/180)a (6)

    Bringing the two equations into the inequality (3) to get 400, there are 400 < (1792 180) a<500, since a is an integer, so simplifying the above equation gives a value of an integer from 41 to 50.

    x and y should also be integers, between 41 and 50 only a takes the value of 45 when x and y are integers, so a = 45

    then x=227 y=221

    Summary. The title is incomplete.

    Xiao Ming and Xiao Dong are fond of stamp collecting, Xiao Ming collected stamps is twice that of Xiao Dong, Xiao Ming gave Xiao Dong 36 stamps, the title is incomplete.

    Is there anything else to follow?

    Xiao Ming and Xiao Dong are both fond of stamp collection, and Xiao Ming's collection of stamps is exactly twice that of Xiao Dong. If Xiao Ku Shiming gave Xiao Dong 36 stamps, then the two of them have the same number of stamps.

    Can it be faster?

    Is it okay to hurry up?

    Sorry, I miscalculated.

    Xiao Ming 432 Xiao Dong 360

    Need a process?

    Need. Please send me the process.

    I've learned the equation.

    All I want is an equation!

    Okay, just look at it, and you'll understand that Xiao Dong is set to x, and Xiao Ming is his double.

    Set up x sheets.

    From the meaning of the topic: 21 + x = 2 (36-x of the penitentiary) 21 + x = 72-2x

    3x=51x=17
