answer this question please ...fast

Answer 1

x = 3/5

y = 5/7  

( x - y )^-1 = 1 / ( x - y)    ||...eq i        

keeping values of 'x' and 'y' in eq i we get

1 / (3/5 - 5/7)  

=  1 / (-4/35)    =  - 35/4        ||...eq ii

1 / x - 1 / y =  5/3 - 7/5

1 / x - 1 / y = 4/15    ||...eq iii

hence proved

eq ii ≠ eq iii
