Answer 1

`@` `\text {Ans}`

`\downarrow`

`2/3 - x + 3/4 = 3`

`2/3 - x = 3 - 3/4`

`2/3 - x = 9/4`

`x = 2/3 - 9/4`

`x =-19/12`

Vậy, `x = -19/12.`

Answer 2

ai giúp mình với

Answer 3

\(\dfrac{2}{3}-x+\dfrac{3}{4}=3\)

\(\left(\dfrac{2}{3}+\dfrac{3}{4}\right)-x=3\)

\(\dfrac{17}{12}-x=3\)

\(x=\dfrac{17}{12}-3\)

\(x=-\dfrac{19}{12}\)
