Answer 1

0,44 x (\(x+x\times\) 5 - \(\dfrac{23}{55}\)) + \(\dfrac{3}{14}\) x 2,24 = 1

 0,44 x (\(x+x\times\)5 - \(\dfrac{23}{55}\)) + 0,48 = 1

 0,44 x (\(x+x\times\) 5 - \(\dfrac{23}{55}\)) = 1 - 0,48

0,44 x (\(x+x\times5\) - \(\dfrac{23}{55}\)) = 0,52

           \(x+x\times5\) - \(\dfrac{23}{55}\) = 0,52 : 0,44

          \(x\) x (1 + 5) -\(\dfrac{23}{55}\)  = \(\dfrac{13}{11}\)

         \(x\) x 6 - \(\dfrac{66}{10}\) = \(\dfrac{13}{11}\) + \(\dfrac{23}{55}\)

         \(x\) x 6 = \(\dfrac{65}{55}\) + \(\dfrac{23}{55}\)

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

         \(x\) x 6 = \(\dfrac{8}{5}\)  : 6

          \(x\)      = \(\dfrac{4}{15}\)

Vậy \(x=\dfrac{4}{15}\)
