Answer

$y\approx0.42$

Work Step by Step

Multiplying both sides by the $LCD= 3.2y ,$ then the solution to the given equation, $ \dfrac{10.6}{y}-14.7=\dfrac{9.92}{3.2}+7.6 ,$ is \begin{array}{l}\require{cancel} 3.2(10.6)-3.2y(14.7)=y(9.92)+3.2y(7.6) \\\\ 33.92-47.04y=9.92y+24.32y \\\\ -47.04y-9.92y-24.32y=-33.92 \\\\ -81.28y=-33.92 \\\\ y=\dfrac{-33.92}{-81.28} \\\\ y\approx0.42 .\end{array}
