Question

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

Giúp mình nha . Cảm ơn !

Answer 1

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

\(\frac{5}{6}-x=\frac{-7}{12}+\frac{8}{12}\)

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

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

         \(x=\frac{10}{12}-\frac{1}{12}\)

         \(x=\frac{9}{12}\)  \(=\frac{3}{4}\)

Answer 2

<=> 5/6 - x = 1/12

<=> -x = 1/12 - 5/6

<=> -x = -3/4

=> x = 3/4

Vậy x = 3/4
