Adding the two equations
3x + 6y + 3x - 6y = 36+0
6x = 36 
x = 6
.
subtracting second equation from first
(3x + 6y ) - (3x-6y) =36 -0
12y = 36
y = 3
.
therefore 
x = 6 and y = 3
(6,3)

Hi there!
3/4 of sugar is needed for 6 servings. 
1/8 x 6 = 6/8 simplify it and you get 3/4.
So 3/4 is your answer.
Hope this helps ;D
        
                    
             
        
        
        
You have to make the percent a decimal by moving the decimal to the left twice. then you need to multiply the other number.
