Giải gấp hộ mik cái

4/3.(x-1/4)=3/2.(2x-1)

 

Answer 1

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

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

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

\(\Leftrightarrow-\frac{5}{3}x=-\frac{7}{6}\)

\(\Leftrightarrow x=\left(-\frac{7}{6}\right)\div\left(-\frac{5}{3}\right)\)

\(\Leftrightarrow x=\frac{7}{10}\)

Answer 2

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

\(\Rightarrow\frac{4}{3}x-\frac{1}{3}-3x+\frac{3}{2}=0\)

\(\Rightarrow-\frac{5}{3}x+\frac{7}{6}=0\)

\(\Rightarrow-\frac{5}{3}x=-\frac{7}{6}\)

\(\Rightarrow x=\frac{7}{10}\)
