Question

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

Answer 1

Không lm đc bài này thì đừng có xưng là hs lớp 6, lớp 7

Answer 2

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\dfrac{5}{6}x=1,2-2.3\)

\(\dfrac{5}{6}x=\dfrac{8}{15}\)

\(x=\dfrac{8}{15}:\dfrac{5}{6}\)

\(x=\dfrac{16}{25}\)

Answer 3

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\Rightarrow\dfrac{6}{5}-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\Rightarrow\dfrac{5}{6}x=\dfrac{6}{5}-\dfrac{2}{3}\)

\(\Rightarrow\dfrac{5}{6}x=\dfrac{8}{15}\)

\(\Rightarrow x=\dfrac{8}{15}:\dfrac{5}{6}\Rightarrow x=\dfrac{16}{25}\)

Answer 4

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\dfrac{5}{6}x=1,2-\dfrac{2}{3}\)

\(\dfrac{5}{6}x=\dfrac{1}{6}\)

\(x=\dfrac{1}{6}:\dfrac{5}{6}\)

\(x=\dfrac{1}{5}\)

Answer 5

suy nghĩ kĩ trước khi đăng nha bạn mình nghĩ nó cũng dễ thôi

Answer 6

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\Leftrightarrow-\dfrac{5}{6}x=\dfrac{-8}{15}\)

\(\Rightarrow x=\dfrac{16}{25}\)

Answer 7

\(1,2-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\Leftrightarrow\dfrac{6}{5}-\dfrac{5}{6}x=\dfrac{2}{3}\)

\(\Leftrightarrow\dfrac{5}{6}x=\dfrac{6}{5}-\dfrac{2}{3}\)

\(\Leftrightarrow\dfrac{5}{6}x=\dfrac{8}{15}\)

\(\Rightarrow x=\dfrac{8}{15}\div\dfrac{5}{6}\)

\(\Rightarrow x=\dfrac{16}{25}\)
