Answer 2

$\huge \fcolorbox{red}{cyan}{y = 3}$

Step-by-step explanation:

$= > \frac{y {}^{2} + 6}{8 {y}^{2} + 3 } = \frac{1}{5} \\ = > \bf{by \: cross \: multiplication} \\ = > 5( {y}^{2} + 6) = 8 {y}^{2} + 3 \\ = > 5 {y}^{2} + 30 = 8 {y}^{2} + 3 \\ = > 5 {y}^{2} - 8 {y}^{2} = 3 - 30 \\ = > - 3 {y}^{2} = - 27 \\ = > {y}^{2} = \frac{ - 27}{ - 3} \\ = > {y}^{2} = 9 \\ = > y = \sqrt{9} \\ = > \boxed{y = 3}$
