Hey there, Xs4etsmith!
The correct answer would be the second option.
To solve for this system of equation, we need to make both equations equal to each other but first we need to make each equation equal to 0.
So,
goes to 
(I subtracted 
from both sides)
And
goes to 
(I subtracted 
from both sides)
Now we can make them equal to each other.
(I subtracted y from both sides to cancel it)
(I subtracted x from both sides)
(I added 3z to both sides to isolate x)
Now, we replace the value of
for and solve
(Distribute)
(Add to both sides)
So
is equal to 
Let's try the second equation
(Add to both sides)
The value of would be 
and when solving both equations, we get the same value for which is

Answer:
7.5 liters of a 40% sugar solution
Step-by-step explanation:
Let
x ----> liters of a 40% sugar solution
Remember that
we know that
The amount of liters of a 40% sugar solution (x) multiplied by 0.40 plus the amount of liters of a 60% sugar solution (30 L) multiplied by 0.60 must be equal to the total amount of liters mixed (x+30) multiplied by 0.56
solve for x
