- ( x + 89 ) + 127 = -18
-x - 89 + 127 = -18
-x + 38 = -18
-x = -18 - 38
-x = -56
x = 56
Vậy x = 56
Tham khảo nha !!!
-(X + 89 ) = -18 - 127
- ( X + 89 ) = -145
-X =-145 - 89
- X = -234
-(x + 89 ) + 127 = -18
-(x + 89 ) = -18 - 127
-(x + 89 ) = - 145
-x - 89 = -145
-x = -145 + 89
-x = -56
x = 56
-(x+89)+127=-18
-x-89+127=-18
-x+38=-18
-x=-18-38
-x=56
x=56 nha bạn
-(X+89)+127=-18
-X-89+127=-18
-X+38 = -18
-X = -18 -38
-X = 56
\(-\left(x+89\right)+127=-18\)
\(-x-89+127=-18\)
\(-x+38=-18\)
\(-x=-56\)
\(x=56\)
-(x+89)+127=-18
-x-89+127=-18
-x+38=-18
-x=-18-38
-x=-56
x=56
