Answer 2

Question -

The positve value of y for which $\rm \dfrac{ {y}^{2} + 6}{8 {y}^{2} + 3 } = \dfrac{1}{5}$

Answer -

➩ $\rm \dfrac{ {y}^{2} + 6}{8 {y}^{2} + 3 } = \dfrac{1}{5}$

➩ $\rm 5({y}^{2} + 6) = 8 {y}^{2} + 3$

➩ $\rm 5y^2 + 30 = 8y^2 + 3$

➩ $\rm 8y^2 - 5y^2 = 30 - 3$

➩ $\rm 3y^2 = 27$

➩ $\rm y^2 = \frac{27}{3}$

➩ $\rm y^2 = 9$

➩ $\rm y = \sqrt{9}$

➩ $\boxed{\rm y = 3}$
