1.Tìm x biết:

a)\(\dfrac{2}{3}.x-\dfrac{3}{2}.x=\dfrac{5}{12}\)

Answer 1

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

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

\(\Rightarrow\dfrac{-5}{6}x=\dfrac{5}{12}\)

\(\Rightarrow x=\dfrac{-1}{2}\)

Answer 2

a)$\frac{2}{3}.x-\frac{3}{2}.x=\frac{5}{12}$

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

=> \(-\dfrac{5}{6}.x=\dfrac{5}{12}\)

=> x = \(-\dfrac{1}{2}\)
