Bài 2 : a) x-11=185-(132+185) b)18-(x+14):3=27

`a, x - 11 = 185 - (132 + 185)`

`=> x -11 = 185 - 132 - 185`

`=> x -11 = -132`

`=> x = -132 + 11`

`=> x = -121`

Vậy `x = -121`

`b, 18 - (x + 14): 3 = 27`

`=> (x + 14) : 3 = 18 - 27`

`=> (x + 14) : 3=  -9`

`=> x + 14 = -9 .3`

`=> x + 14 = -27`

`=> x = -27 - 14`

`=> x = -41`

Vậy `x = -41`
