Question

tìm x: x-[17/2 - (-3/7 + 5/3)] = -1/3

Answer 1

\(x-\left[\dfrac{17}{2}-\left(\dfrac{-3}{7}+\dfrac{5}{3}\right)\right]=\dfrac{-1}{3}\)

\(x-\left(\dfrac{17}{2}-\dfrac{26}{21}\right)=\dfrac{-1}{3}\)

\(x-\dfrac{305}{42}=\dfrac{-1}{3}\)

       \(x=\dfrac{-1}{3}+\dfrac{305}{42}\)

       \(x=\dfrac{97}{14}\)

Answer 2

`@` `\text {Ans}`

`\downarrow`

`x-[17/2 - (-3/7 + 5/3)] = -1/3`

`=> x - (17/2-26/21) = -1/3`

`=> x-305/42 = -1/3`

`=> x=-1/3 + 305/42`

`=> x=97/14`

Vậy, `x=97/14.`
