Question

2/3.x-3/2.(x-1/2)=5/12

1,5-2x.(-1 4/7)=11/4

Answer 1

\(\frac{2}{3}.x-\frac{3}{2}.\left(x-\frac{1}{2}\right)=\frac{5}{12}\)

\(\Leftrightarrow\frac{2}{3}.x-\frac{3}{2}.x+\frac{3}{4}=\frac{5}{12}\)

\(\Leftrightarrow x.\left(\frac{2}{3}-\frac{3}{2}\right)=\frac{5}{12}-\frac{3}{4}\)

\(\Leftrightarrow x.\frac{-5}{6}=\frac{-4}{12}\)

\(\Leftrightarrow x=\frac{-4}{12}:\frac{-5}{12}\)

\(\Leftrightarrow x=\frac{4}{5}\)

Vậy : \(x=\frac{4}{5}\)
