Answer 2

\(\frac{3}{\frac{1}{4}}x-\frac{1}{\frac{2}{3}}=\frac{5}{12}-\frac{7}{6}x\)

\(3:\frac{1}{4}x-1:\frac{2}{3}=\frac{5}{12}-\frac{7}{6}x\)

\(1x-1.5=\frac{5}{12}-\frac{7}{6}x\)

\(1x+\frac{7}{6}x=1.5+\frac{5}{12}\)

\(\left(1+\frac{7}{6}\right)x=\frac{18}{12}+\frac{5}{12}=\frac{23}{12}\)

\(\frac{13}{6}x=\frac{23}{12}\)

\(x=\frac{23}{12}:\frac{13}{6}\)

\(x=\frac{23}{12}\cdot\frac{6}{13}=\frac{23}{26}\)
