Question

Answer 1

\(x+\dfrac{15}{6}=\dfrac{41}{10}\) 

        \(x=\dfrac{41}{10}-\dfrac{15}{6}\) 

        \(x=\) \(\dfrac{8}{5}\)

Answer 2

\(x+\dfrac{15}{6}=\dfrac{41}{10}\\ x=\dfrac{41}{10}-\dfrac{15}{6}\\ x=\dfrac{8}{5}\)

Answer 3

chọn `x = 8/5 ` 

 

giải thích : 

 

`x+15/6=41/10`

 

`x=41/10 - 15/6 `

 

`x=123/30 - 75/30 `

 

`x= 48/30 = 8/5 `

 

Vậy `x= 8/5`
