Question

Giải phương trình sau:

\(\frac{-5}{8}-x=\frac{-3}{20}-\left(\frac{-1}{6}\right)\)

Answer 1

Ta có: \(-\frac{5}{8}-x=-\frac{3}{20}-\left(-\frac{1}{6}\right)\)

\(\Rightarrow-\frac{5}{8}-x=-\frac{3}{20}+\frac{1}{6}\)

\(\Rightarrow x=-\frac{5}{8}-\left(-\frac{3}{20}+\frac{1}{6}\right)\)

\(\Rightarrow x=-\frac{5}{8}+\frac{3}{20}-\frac{1}{6}\)

\(\Rightarrow x=\frac{-75}{120}+\frac{18}{120}-\frac{20}{120}\)

\(\Rightarrow x=-\frac{77}{120}\)

Vậy \(x=-\frac{77}{120}\)

Chúc bạn hok tốt! 

Answer 2

<=> x=\(-\frac{5}{8}+\frac{3}{20}-\frac{1}{6}=-\frac{77}{120}\)
