K cho  mk nha bn!

a ) (x+74 ) - 218 = 200 \(\Leftrightarrow\) x+74-218 = 200   \(\Leftrightarrow\)   x= 200+218+74   \(\Leftrightarrow\)     x= 492                                                                                                                       vậy x = 492                                                                                                                                                     b, 3636 : ( 12x -91) =36   \(\Leftrightarrow\)12x-91 = 3636: 36  \(\Leftrightarrow\)12x-91 = 101  \(\Leftrightarrow\)    12x = 101+91   \(\Leftrightarrow\) 12x = 192  \(\Leftrightarrow\)  x= 16                                                         vậy x = 16           

 c, ( x : 3   +45 ) . 67 = 8911  \(\Leftrightarrow\)  x : 3 +45 = 8911: 67 \(\Leftrightarrow\)   x : 3 = 133 - 45   \(\Leftrightarrow\)  x : 3 = 88 \(\Leftrightarrow\)   x= 88 . 3  \(\Leftrightarrow\) x=264 

                   vậy x= 264

Tìm x:
3636:(12x-91)=36

(12x-91)=3636:36

(12x-91)=101

12x =101+91

12x = 192

x = 192:12

x =16

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

Vậy x = 16.
