giup minh nha

ai có câu trả lời đầy đủ mình sẽ tick

Answer 1

\(\frac{x}{2}+x+\frac{x}{3}+x+x+\frac{x}{4}=\frac{23}{12}\)

\(\left(\frac{x}{2}+\frac{x}{3}+\frac{x}{4}\right)+\left(x+x+x\right)=\frac{23}{12}\)

\(\frac{3x}{12}+\frac{36x}{12}=\frac{23}{12}\)

\(\frac{49x}{12}=\frac{23}{12}\)

\(\frac{49}{12}.x=\frac{23}{12}\)

          \(x=\frac{23}{12}:\frac{49}{12}=\frac{23}{49}\)
