[Nguyễn Mỹ Hoa]

MẤY BẠN ƠI GIÚP MIK CÂU NÀY NHA

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

Answer 1

[Lê Tài Bảo Châu]

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

\(\Leftrightarrow\left(2-x\right).3=\left(3x-1\right).4\)

\(\Leftrightarrow6-3x=12x-4\)

\(\Leftrightarrow-3x-12x=-4-6\)

\(\Leftrightarrow-15x=-10\)

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

Vậy ...

Answer 2

[Ngọc Nguyễn]

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

\(3.\left(2-x\right)=4.\left(3x-1\right)\)

\(6-3x=12x-4\)

\(-3x-12x=-4-6\)

\(-15x=-10\)

      \(x=\frac{2}{3}\)

Vậy \(x=\frac{2}{3}\)
