Question

giúp mk vs

3/5.x-x bằng -4/15

tớ cần rất gấp nha

 

Answer 1

\(\frac{3}{5}x-x=\frac{-4}{15}\)

\(\Rightarrow\left(\frac{3}{5}-1\right)x=\frac{-4}{15}\)

\(\Rightarrow\frac{-2}{5}x=\frac{-4}{15}\)

\(\Rightarrow x=\frac{-4}{15}:\frac{-2}{5}=\frac{2}{3}\)

\(\text{vậy x=}\frac{2}{3}\)

Answer 2

\(\frac{3}{5}x-x=-\frac{4}{15}\)

\(\Leftrightarrow-\frac{2}{5}x=-\frac{4}{15}\)

\(\Leftrightarrow x=\left(\frac{-4}{15}\right):\left(-\frac{2}{5}\right)=\frac{2}{3}\)
