Question

Xx2+Xx1/6=8/5

giúp mình bài nay nha

Answer 1

X x 2+X x 1/6 =8/5

=> X x (2+1/6)=8/5

=> X x 13/6=8/5

 =>         X  =8/5:13/6

=>         X   =48/65

Answer 2

\(x\times2+x\times\dfrac{1}{6}=\dfrac{8}{5}\)

\(\Leftrightarrow2x\times2\times\dfrac{1}{6}=\dfrac{8}{5}\)

\(\Leftrightarrow2x\times\dfrac{1}{3}=\dfrac{8}{5}\)

\(\Leftrightarrow2x=\dfrac{8}{5}:\dfrac{1}{3}\)

\(\Leftrightarrow2x=\dfrac{8}{5}\times\dfrac{3}{1}\)

\(\Leftrightarrow2x=\dfrac{24}{5}\)

\(\Leftrightarrow x=\dfrac{24}{5}:2\)

\(\Leftrightarrow x=\dfrac{24}{5}\times\dfrac{1}{2}\)

\(\Leftrightarrow x=\dfrac{24}{10}\)

\(\Leftrightarrow x=\dfrac{12}{5}\)
