Question

 (x-\(\frac{1}{3}\))+\(\frac{4}{5}\)=((-3.2)+\(\frac{2}{5}\))

 

 

Answer 1

\(\left(x-\frac{1}{3}\right)+\frac{4}{5}=\left[\left(-3.2\right)+\frac{2}{5}\right]\)

\(\left(x-\frac{1}{3}\right)+\frac{4}{5}=\left(-6+\frac{2}{5}\right)\)

\(\left(x-\frac{1}{3}\right)+\frac{4}{5}=-\frac{28}{5}\)

                 \(x-\frac{1}{3}=-\frac{28}{5}+\frac{4}{5}\)

                  \(x-\frac{1}{3}=-\frac{24}{5}\)

                             \(x=-\frac{24}{5}+\frac{1}{3}\)

                              \(x=-\frac{67}{15}\)

đúng thì k tớ nha bn
