Yes,but solving it:-
2v+3  = k  
4v+5
= 2v+3=4vk+5k
value of k=??? after soving  adn plot in other equation and equialte 
2 1 2

[2v+3]/[4v+5]................1
we divide and multiply by 2
so
{2*[2v+3]}/{2*[4v+5]}
[4v+6]/{2[4v+5]}
so
[4v+5+1]/{2[4v+5]}
1/2{1+1/[4v+5]}
1/2 +1/{2[4v+5]}....................3
which is same as ans
