The correct answer is the first option.
If you want to use elimination, you can sum the two equations for example, so that the x's simplify:



Plug this value for y in one of the equations to derive the value of x:

So, the solution is 
 
        
             
        
        
        
Answer:
5.2%.
Step-by-step explanation:
After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.
So we have 420 gallons of 6%  and 280 gallons of 4% after 1 hour.
So the strength at that time =  (420* 6) + 280*4) / 700
= 5.2%.
