Answer 1

\(\Leftrightarrow\left(\dfrac{8}{9}+\dfrac{4}{9}-\dfrac{7}{9}\right)\times x=\dfrac{11}{10}\)

\(\Leftrightarrow\dfrac{5}{9}\times x=\dfrac{11}{10}\)

\(\Leftrightarrow x=\dfrac{11}{10}:\dfrac{5}{9}=\dfrac{99}{50}\)

Answer 2

= \(\left(\dfrac{8}{9}+\dfrac{4}{9}-\dfrac{7}{9}\right)x\) x = \(\dfrac{11}{10}\)

= \(\dfrac{5}{9}\) x \(x\) =\(\dfrac{11}{10}\)

= \(x=\dfrac{11}{10}:\dfrac{5}{9}=\dfrac{99}{50}\)

Answer 3

x = 99/50
