Question

2/3×x+1/2=1/10

Answer 1

\(\frac{2}{3}\times x+\frac{1}{2}=\frac{1}{10}\)

\(\Rightarrow\frac{2}{3}\times x=\frac{1}{10}-\frac{1}{2}\)

\(\Rightarrow\frac{2}{3}\times x=-\frac{2}{5}\)

\(\Rightarrow x=-\frac{2}{5}:\frac{2}{3}\)

\(\Rightarrow x=-\frac{2}{5}.\frac{3}{2}\)

\(\Rightarrow x=-\frac{3}{5}\)

Answer 2

\(\frac{2}{3}\) . x + \(\frac{1}{2}\) = \(\frac{1}{10}\)

=> \(\frac{2}{3}\) . x  = \(\frac{1}{10}\) - \(\frac{1}{2}\) = \(\frac{-2}{5}\)

=> x= \(\frac{-2}{5}\) : \(\frac{2}{3}\) = \(\frac{-3}{5}\) Vậy x = \(\frac{-3}{5}\)
