Question

find the positive value of y which satisfies the equation (y²+1)/(y²-1)=5/4​

Answer 1

Answer:

Step-by-step explanation:

4($y^{2}$ + 1) = 5($y^{2$ - 1)                                     --- cross multiplication

4$y^{2}$ + 4 = 5$y^{2}$ - 5                                       --- distributive property

4 + 5 = 5$y^{2}$ - 4$y^{2}$                              ---transporting -5 to L.H.S and 4$y^{2}$ to R.H.S

9 = $y^{2}$                                                        --- simplifying

y = 3 , -3                                                    --- finding square root

Answer 2

answer is 3

4y²+4=5y²-5

y²=9

y= 3
