Question

xx2/7-2/3=1/2

Answer 1

x\(.\frac{2}{7}-\frac{2}{3}=\frac{1}{2}\)

= \(x.\frac{2}{7}=\frac{1}{2}+\frac{2}{3}\)

\(=x.\frac{2}{7}=\frac{7}{6}\)

\(x=\frac{7}{6}:\frac{2}{7}\)

x = \(\frac{49}{12}\)

Answer 2

xchia 5/4+4/5=2

Answer 3

\(x.\frac{2}{7}-\frac{2}{3}=\frac{1}{2}\)

\(\Rightarrow x.\frac{2}{7}=\frac{1}{2}+\frac{2}{3}\)

\(\Rightarrow x.\frac{2}{7}=\frac{7}{6}\)

\(\Rightarrow x=\frac{7}{6}:\frac{2}{7}\)

\(\Rightarrow x=\frac{49}{12}\)
