There is no solution.

Answer 1

To solve the system of equations using the elimination method, we start with the given equations:

1. \( 4x + 2y = 6 \)
2. \( x - 4y = -12 \)

Let's simplify the first equation:

1. \( 4x + 2y = 6 \) can be divided by 2:
\[ 2x + y = 3 \] (Equation 1)

Now we rewrite the second equation:
2. \( x - 4y = -12 \) can be left as is:
\[ x - 4y = -12 \] (Equation 2)

Next, we can express \( y \) in terms of \( x \) using Equation 1:
\[ y = 3 - 2x \]

Now, let's substitute this expression for \( y \) back into Equation 2:

\[
x - 4(3 - 2x) = -12
\]

Expanding and simplifying:

\[
x - 12 + 8x = -12
\]
\[
9x - 12 = -12
\]
Adding 12 to both sides:
\[
9x = 0
\]
Now, solving for \( x \):

\[
x = 0
\]

Next, we substitute \( x = 0 \) back into the expression for \( y \):

\[
y = 3 - 2(0) = 3
\]

Thus, the solution to the system of equations is:

\[
(x, y) = (0, 3)
\]

So, the correct response is:

**The solution is (0, 3).**
