50-(30.8+4.9)=14.3 kg.
You start with 50 then you need to subtract 30.8 and 4.9 from it. So you add them together and get 35.7. Then you subract 25.9 from 50 and get 14.3 kg.
        
                    
             
        
        
        
Step-by-step explanation:
{9x+3y=-36
y=-3x-21
9x-9x-36=-36
y=-3x-21
x=0
y=-21
