k mk nha

câu 1:

3636:(12*x-91)= 36

          12*x-91=3636:36

          12*x-91=101

          12*x     =101 + 91

          12*x     =192

               x     =192 : 12

               x     =16

câu 2:

(x:23+45)*67=8911

 x:23+45     =8911 : 67

 x:23+45     =133

x:23           =133 - 45

x:23           = 88
