Question

X x4+4/5=17/6 - 2/5

Answer 1

\(x.4+\frac{4}{5}=\frac{73}{30}\)

\(x.4=\frac{49}{30}\)

\(x=\frac{49}{30}.\frac{1}{4}\)

\(x=\frac{49}{120}\)

Answer 2

Ta có:

X x4+\(\frac{4}{5}=\frac{17}{6}-\frac{2}{5}\)

X x4=\(\frac{17}{6}-\frac{2}{5}-\frac{4}{5}\)

X x4=\(\frac{17}{6}-\frac{6}{5}\)

Xx4=\(\frac{49}{30}\)

X=\(\frac{49}{120}\)

Answer 3

X.4 + 4/5 =17/6 - 2/5

4x + 4/5 = 73/30

4x            = 73/30 - 4/5

4x           = 49/30

x              = 49/30 ÷4

x              = 49/120

Vậy x = 49/120
