Question

Tìm x

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

Nhanh nha mk đang cần gấp nhé

Answer 1

\(\Leftrightarrow\frac{3x}{6}+\frac{5}{6}=\frac{-4}{6}\)

\(\Leftrightarrow3x+5=-4\)

\(\Leftrightarrow3x=-9\)

\(\Leftrightarrow x=-3\)

Answer 2

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

\(\Rightarrow\frac{x}{2}=\frac{-2}{3}-\frac{5}{6}=\frac{-4}{6}-\frac{5}{6}=\frac{-4-5}{6}=\frac{-9}{6}=\frac{-3}{2}\)

\(\Rightarrow\frac{x}{2}=\frac{-3}{2}\)

\(\Rightarrow x=-3\)

Answer 3

x/2 + 5/6 = -2/3

         x/2 = -2/3 - 5/6

         x/2 = -3/2

=> x = -3
