Question

X : 0,5 + X x 1/5 = 1/3/5 tìm x

Answer 1

\(x:0,5+x\) . \(\dfrac{1}{5}=1\dfrac{3}{5}\)

\(x :\)\(\dfrac{1}{2}+x.\dfrac{1}{5}=\dfrac{8}{5}\)

\(x . 2+x.\)\(\dfrac{1}{5}=\dfrac{8}{5}\)

\(x\)\((\)\(2+\)\(\dfrac{1}{5}\)\()\) \(=\)\(\dfrac{8}{5}\)

\(x.\)\(\dfrac{11}{5}=\dfrac{8}{5}\)

\(x=\)\(\dfrac{8}{5}:\dfrac{11}{5}\)

\(x=\)\(\dfrac{8}{11}\)

vậy \(x=\)\(\dfrac{8}{11}\)

Answer 2

\(=>x\times\left(2+\dfrac{1}{5}\right)=\dfrac{5}{3}\)

=>\(x\times\dfrac{11}{5}=\dfrac{5}{3}\)

\(x=\dfrac{5}{3}:\dfrac{11}{5}=\dfrac{25}{33}\)
