Answer

y = 1

Work Step by Step

$\frac{2}{y}$+$\frac{1}{2}$=$\frac{5}{2y}$ 2y($\frac{2}{y}$+$\frac{1}{2}$)=2y$\frac{5}{2y}$ 2y$\frac{2}{y}$+2y$\frac{1}{2}$=5 2*2+y=5 4+y=5 y=1 The solution is 1 Check Let x=1 $\frac{2}{y}$+$\frac{1}{2}$=$\frac{5}{2y}$ $\frac{4}{2}$+$\frac{1}{2}$=$\frac{5}{2}$ $\frac{5}{2}$=$\frac{5}{2}$
