Answer:

Let's solve the system of equations algebraically:

4x - 2y = 8

2x - 4y = 4

We can simplify both equations by dividing them by their respective coefficients to make it easier to work with:

Divide equation (1) by 2:

(4x - 2y)/2 = 8/2

2x - y = 4

Divide equation (2) by 2:

(2x - 4y)/2 = 4/2

x - 2y = 2

Now, we have the simplified system of equations:

2x - y = 4

x - 2y = 2

Let's use the method of substitution to solve this system. We'll solve equation (2) for x:

x = 2y + 2

Now, substitute this expression for x into equation (1):

2x - y = 4

2(2y + 2) - y = 4

Simplify and solve for y:

4y + 4 - y = 4

3y + 4 = 4

Subtract 4 from both sides:

3y = 0

Now, divide by 3:

y = 0

Now that we have the value of y, substitute it back into the equation x = 2y + 2:

x = 2(0) + 2

x = 2

So, the solution to the system of equations is (x, y) = (2, 0).

The correct answer is C. (2, 0).
