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
\(x\times2+x\times\dfrac{1}{6}=\dfrac{8}{5}\)
\(\Leftrightarrow2x\times2\times\dfrac{1}{6}=\dfrac{8}{5}\)
\(\Leftrightarrow2x\times\dfrac{1}{3}=\dfrac{8}{5}\)
\(\Leftrightarrow2x=\dfrac{8}{5}:\dfrac{1}{3}\)
\(\Leftrightarrow2x=\dfrac{8}{5}\times\dfrac{3}{1}\)
\(\Leftrightarrow2x=\dfrac{24}{5}\)
\(\Leftrightarrow x=\dfrac{24}{5}:2\)
\(\Leftrightarrow x=\dfrac{24}{5}\times\dfrac{1}{2}\)
\(\Leftrightarrow x=\dfrac{24}{10}\)
\(\Leftrightarrow x=\dfrac{12}{5}\)
sửa hộ chỗ nay thành này nha mình bấm nhanh quá nên hơi lỗi
