I'm not sure But i think that's would be correct
The solution to the given system of linear equations is x = 1, y = 2. That is (1, 2)
<h3>Simultaneous linear equations </h3>
From the question, we are to solve the given system of equations
The given system of equations is
4x + y = 6 -----------(1)
2x - 3y = -4 -----------(2)
From the equation (1)
4x + y = 6
y = 6 - 4x ----------(3)
Substitute the value of y into equation (2)
2x - 3y = -4
2x -3(6 - 4x) = -4
2x -18 +12x = -4
2x + 12x = -4 + 18
14x = 14
x = 14/14
x = 1
Substitute the value of x into equation (3)
y = 6 - 4x
y = 6 - 4(1)
y = 6 - 4
y = 2
Hence, the solution to the given system of linear equations is x = 1, y = 2. That is (1, 2)

If there is nothing missing in your question, the answer is :
0.5y - 10x
If you mix 1 liter of the 10% solution with 1 liter of the 30% solution, you will have 2 liters of 20% solution. Keeping that in mind, you must mix half of the number of liters with 10%, and the other half with 30% in order to get 20%. So knowing all those things, we can do the problem. She needs 15 liters of 20%, so you need to mix 7.5 liters of 10% with 7.5 liters of 30%. After mixing those, you'll have 15 liters of 20% solution. I hope this helps. Please put as brainliest.
D. There is a 5/8 chance each time. You would multiply that together to get the answer seen in D.
