11 - (x + 84 ) = 97
\(\Rightarrow x+84=-86\)
\(\Rightarrow x=-170\)
11 - (x + 84) = 97
(x + 84) = 11 - 97
(x + 84) = -86
x = -86 - 84
x = -170
Trả lời:
11 - (x + 84) = 97
x + 84 = -86
x = -170
Vậy x = -170

11- (x + 84) = 97
x +84 =11-97
x +84= -84
11- ( x+84) = 97
x + 84= 11-97
x+ 84= -84
x = -84 -84
x = - 168
