173 - ( x - 49 ) = 27
Tìm X
x-49=173-27
x-49=146
x=146+49
x=195
Vậy x=195
173 - ( x - 49 ) = 27
x - 49 = 173 - 27
x - 49 = 146
x = 146 + 49
x = 195
Vậy x = 195
x-49= 173-27
x-49= 146
x = 146+49
x = 195
173 - [ x / 49 ] = 27
173 - (x / 49) = 27
x / 49 = 146
x = 146 x 49
x = 7154
173-[ x/49] =27
x /49=173-27
x /49=146
x=146.49
x=7154
