\(154\)\(:\) \(x\)\(=\)\(38\)( dư 2 )
\(x\) \(=\) \(\left(154-2\right)\)\(:\)\(38\)
\(x\) \(=\) \(152\) \(:\)\(38\)
\(x\) \(=\) \(4\)
154 : x = 38 ( dư 2 )
x = ( 154 - 2 ) : 38
x = 152 : 38
x = 4
154 : x = 38 ( dư 2 )
x = ( 154 - 2 ) : 38
x = 152 : 38
x = 4
154 : x = 38 ( dư 2 )
x = ( 154 - 2 ) : 38
x = 152 : 38
x = 4
Vậy x = 4
