Các bn giúp mk với mk cần gấp làm chi tiết hộ mk nha

Answer 1

[Anh Alay]

\(4x-\left(x+\frac{1}{2}\right)=2x-\left(\frac{1}{2}x-5\right)\)

\(\Leftrightarrow4x-x-\frac{1}{2}=2x-\frac{1}{2}x+5\)

\(\Leftrightarrow4x-x-2x+\frac{1}{2}x=5-\frac{1}{2}\)

\(\Leftrightarrow\frac{3}{2}x=\frac{9}{2}\Leftrightarrow x=3\)
