Answer: Yes 
Step-by-step explanation:
2x+8y=6
 -8y -8y
2x = -2y 
Divide by two so x will be by itself, so the answer will be -1y.
5x+20y=2
 -20y -20y
5x = -18y 
Divide by 5 so x will be by itself, so the answer will be -3y.
 
        
             
        
        
        
Already have: 3/6 cups
need : 1/5
3/6 - 1/5=
15/30 - 6/30=
9/30=
3/10
so you wil have 3/10 of brown sugar left
        
             
        
        
        
5 = what percent of 23
5 = x% of 23
5 = (x/100)*23
5 = 23x/100
5*100 = 23x
23x = 5*100
x = 5*100/23
x = 21.739
5 is ≈ 21.739% of 23
