Answer 1

`54 : x + 20 = 56`

`54 : x = 56-20`

`54:x = 36`

`x=54 : 36`

`x=1,5`

Answer 2

\(54:x+20=56\)

\(54:x=56-20\)

\(54:x=36\)

\(x=54:36\)

\(x=\) \(\dfrac{\text{54}}{36}\)

Answer 3

54 : X + 20 = 56

54 : X          = 56 - 20

54 : X          = 36

       X          = 54 : 36

       X          = 1,5

vậy X = 1,5
