Question

2/5* y + y * 1/5 =2/7

Answer 1

\(\frac{2}{5}\times y+y\times\frac{1}{5}=\frac{2}{7}\)

\(\left(\frac{2}{5}+\frac{1}{5}\right)\times y=\frac{2}{7}\)

\(\frac{3}{5}\times y=\frac{2}{7}\)

\(y=\frac{2}{7}:\frac{3}{5}\)

\(y=\frac{10}{21}\)

Answer 2

2/5*y+y*1/5=2/7

y*(2/5+1/7)=2/7

y*19/35=2/7

y          =2/7:19/35

y          = 10/19
