1/3 - 5/6 ( x + 1 ) = 0,5
1/3 - 5/6 ( x + 1 ) = 1/2
5/6 ( x + 1 ) = 1/3 - 1/2
5/6 ( x + 1 ) = -1/6
x + 1 = -1/6 : 5/6
x +1 = -1/5
x = -1/5 - 1
x = -6/5
\(\frac{1}{3}-\frac{5}{6}.\left(x+1\right)=0.5\)
\(\frac{5}{6}.\left(x+1\right)=\frac{1}{3}-0.5\)
\(\frac{5}{6}.\left(x+1\right)=\frac{-1}{6}\)
\(x+1=\frac{-1}{6}:\frac{5}{6}\)
\(x+1=\frac{-1}{5}\)
\(x=\frac{-1}{5}-1\)
\(x=\frac{-6}{5}\)
Vậy \(x=\frac{-6}{5}\)
