Question

Tìm x :

( x - \(\frac{3}{5}\) ) : ( x - 0,5 ) = \(\frac{2}{3}\)

Answer 1

=>(x - 0,6)*3=(x-0,5)*2

=>3*x-1,8=2*x-1

=>3*x-2*x=1,8-1

=>x=0,8

Vậy x=0,8

Answer 2

\(\left(x-\frac{3}{5}\right):\left(x-0,5\right)=\frac{2}{3}\)

\(x-\frac{3}{5}=\frac{2}{3}\left(x-0,5\right)\)

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

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

\(-\frac{1}{3}x=-\frac{4}{15}\)

\(x=\frac{4}{5}\)
