Question

tìm x

2/3x - 3/2x = 5/12

Answer 1

\(\frac{2}{3}x-\frac{3}{2}x=\frac{5}{12}\)

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

\(x.\left(-\frac{5}{6}\right)=\frac{5}{12}\)

\(x=\frac{5}{12}.\left(-\frac{5}{6}\right)\)

\(x=-\frac{25}{72}\)

Vậy \(x=-\frac{25}{72}\)

Answer 2

x dưới mẫu hả em

Answer 3

\(\frac{2}{3}x-\frac{3}{2}x=\frac{5}{12}\)

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

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

 \(x=\frac{5}{12}:\frac{-5}{6}\)

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