3.(10.x)=111
=> 10x = 111 : 3
=> 10 x = 37
=> x = 37 : 10
=> x = \(\frac{37}{10}\)
3.(10.x)=111
(10.x)=111:3
(10.x)=37
x=37:10
x=3,7
vậy x=3,7
\(3.\left(10.x\right)=111\)
\(10.x=111:3\)
\(10.x=37\)
\(x=37:10\)
\(x=\frac{37}{10}\)

3 . ( 10 . x ) = 111
10 . x = 111 : 3
10 . x = 37
x = 37 : 10
x = 3,7
vậy x = 3,7
