If 2x-3 is the smallest, then the other three are 2x-1 , 2x+1 , and 2x+3. 

If we add them all, we have
2x-3 + 2x-1 + 2x+1 + 2x+3 = 8x

Their sum is 8x. 
Note: we cannot find a specific value for this since there was no given value for x.

I'll try my best to answer it correctly. my understanding to your question is the four consecutive odd number should be add. 1+3+5+7 = 16. your problem is 2x - 3. 
2(1)-3+16= 15
