Question

x: ( 3và1/2 -5và1/6 ) = 4và1/2 - 6và2/3

Answer 1

\(x:\left(3\dfrac{1}{2}-5\dfrac{1}{6}\right)=4\dfrac{1}{2}-6\dfrac{2}{3}\)

\(\Rightarrow x:\left(\dfrac{7}{2}-\dfrac{31}{6}\right)=\dfrac{9}{2}-\dfrac{20}{3}\)

\(\Rightarrow x:\dfrac{-5}{3}=\dfrac{-13}{6}\)

\(\Rightarrow x=\dfrac{-13}{6}\cdot\dfrac{-5}{3}\)

\(\Rightarrow x=\dfrac{65}{18}\)
