Given :   14y²-6y+8/10y²+4y+7 = 7y-3/5y+2​

To Find :  Check its true or not

Solution:

y²-6y+8/10y²+4y+7 = 7y-3/5y+2​

cross multiply

=> (y²-6y+8) (5y+2​ ) =(10y²+4y+7)(7y - 3)

=>  (y²-6y+8)5y +  (y²-6y+8)2  = (10y²+4y+7)7y  - (10y²+4y+7)3

=> 5y³ - 30y² + 40y + 2y²  -12y + 16  =70y³  + 28y²  + 49y  - 30y² - 12y - 21

=> 5y³ - 28y² + 28y + 16  =70y³  -2y²  + 37y  - 21

=>  65y³ + 26y²  + 9y  - 37 = 0

Hence LHS ≠ RHS

so this is not true
