 Tim x, biết: 

Answer 1

\(x+\frac{1}{2}=\frac{1}{4}+\frac{2}{4}\)

\(x=\frac{1}{4}+\frac{1}{2}-\frac{1}{2}\)

\(x=\frac{1}{4}\)

Answer 2

\(x+\frac{1}{2}=\frac{1}{4}+\frac{2}{4}\Rightarrow x+\frac{1}{2}=\frac{3}{4}\Rightarrow x=\frac{1}{4}\)

Tick đúng cho mk nha!!!!!!!!!

Answer 3

\(x+\frac{1}{2}=\frac{1}{4}+\frac{2}{4}\)

\(x+\frac{1}{2}=\frac{3}{4}\)

          \(x=\frac{3}{4}-\frac{1}{2}\)

          \(x=\frac{1}{4}\)
