If I'm reading what you wrote correctly, it's this

If matrix%281%2C2%2Clim%2C+%28%22f%28x%29%22%2F%28x-2%29%29%29%22%22=%22%225, f%28x%29%2F%282x-1%29=15%2F4, then 

The first part makes no sense because there is nothing given for x to approach
in the limit.  So I can only ignore that, and consider it as

If f%28x%29%2F%282x-1%29=15%2F4, then 


f%28x%29%2F%282x-1%29=15%2F4

4f%28x%29=15%282x-1%29

f%28x%29=expr%2815%2F4%29%282x-1%29

%22%22=%22%22%22%22=%22%22

Make a change of variable x+1=y, x=y-1

%22%22=%22%22

%22%22=%22%22

%22%22=%22%22

%22%22=%22%22expr%2815%2F4%29%2A2%22%22=%22%2215%2F2

This post either is presented/written incorrectly, or its meaning is dark and unclear.

Or BOTH.
