Answer

y = 5

Work Step by Step

$\frac{6}{3y}$+$\frac{3}{y}$=1 3y($\frac{6}{3y}$+$\frac{3}{y}$)=1*3y 3y$\frac{6}{3y}$+3y$\frac{3}{y}$=3y 6+3*3=3y 6+9=3y 15=3y y=5 The solution is 5 Check Let x=5 $\frac{6}{3y}$+$\frac{3}{y}$=1 $\frac{6}{3*5}$+$\frac{3}{5}$=1 $\frac{6}{15}$+$\frac{9}{15}$=1 $\frac{15}{15}$=1 1=1
