2448 : [119 - (x - 6)] = 24
[119 - (x - 6)] = 2448 : 24
[119 - (x - 6)] = 102
(x - 6) = 119 - 102
x - 6 = 17
x = 17 + 6
x = 23
2448 : { 119 - ( x - 6 ) } = 24
119 - ( x - 6 ) = 2448 : 24
119 - ( x - 6 ) = 102
x - 6 = 119 - 102
x - 6 = 17
x = 17 - 6
x = 11
2448 : [ 119 - ( x - 6 ) ] = 24
<=> [ 119 - ( x -6)] = 2448 : 24
<=> [ 119 - ( x - 6 )] = 102
<=> x - 6 = 119 - 102
<=> x -6 = 17
<=> x = 17 + 6
<=> x = 23
Vậy...
\(2448:\left[119-\left(x-6\right)\right]=24\)
\(119-\left(x-6\right)=2448:24\)
\(119-\left(x-6\right)=102\)
\(x-6=119-102\)
\(x-6=17\)
\(x=17+6\)
\(x=23\)
