Question

x+19=54-34

x.3=18:9

Answer 1

`x + 19 = 54 - 34`

`=> x + 19 = 20`

`=> x = 20 - 19`

`=> x = 1`

`x * 3 = 18 : 9`

`=> x * 3 = 2`

`=> x = 2 : 3`

`=> x = 2/3`

Answer 2

-, \(x+19=54-34\)

\(x+19=20\)

\(x=20-19\)

\(x=1\)

Vậy \(x=1\)

-, \(x.3=18:9\)

\(x.3=2\)

\(x=2:3\)

\(x=\dfrac{2}{3}\)

Vậy \(x=\dfrac{2}{3}\)
