Số cam còn lại sau lần bán thứ 2 là:

        ( 24 + 3/4 ) : 3/4 = 33 (quả )

Số cam còn lại sau lần bán thứ nhất là :

        ( 33 + 1/3) : 2/3 = 50 (quả )

Số cam bác nông dân đem đi bán là :

        ( 50 + 1/2 ) : 1/2 = 101 ( quả )

                     Đáp số : 101 quả 

cua the ki 82 ki nhe

= 19 nhân ( 28 + 72 )

= 19 nhân 100

= 1900

so 1267 la so du trong phep chia cho 1292

\(2x\left(3y-2\right)+\left(3y-2\right)=-55\)

\(\left(3y-2\right)\left(2x+1\right)=-55\)

=> -55 chia hết cho 3y-2 và 2x+1 <=> 55chia hết cho 3y-2 và 2x+1

\(\Rightarrow3y-2\inƯ\left(55\right)\)và \(2x+1\inƯ\left(55\right)\)

Mà \(Ư\left(55\right)=\left\{-55;-11;-5;-1;1;5;11;55\right\}\)

Mặt khác 3y-2 chia 3 dư -2 (hay chia 3 dư1)

\(\Rightarrow3y-2\in\left\{-11;-5;1;55.\right\}\) 

Ta có bảng sau

Vậy các cặp (x;y) cần tìm là :(2;-3),(5;-1),(-28;1),(0;19).
