Solution Steps
To solve the system of equations using the elimination method, we aim to eliminate one of the variables by adding or subtracting the equations. Here, we can add the two equations to eliminate \(x\) because the coefficients of \(x\) are opposites. After eliminating \(x\), we solve for \(y\) and then substitute back to find \(x\).
Step 1: Write the System of Equations
We start with the following system of equations:
\[
\begin{align*}
& \quad 6x + 4y = -16 \\
& \quad -6x + y = 41
\end{align*}
\]
Step 2: Eliminate One Variable
To eliminate \(x\), we can add both equations:
\[
(6x + 4y) + (-6x + y) = -16 + 41
\]
This simplifies to:
\[
5y = 25
\]
Step 3: Solve for \(y\)
Dividing both sides by 5 gives:
\[
y = 5
\]
Step 4: Substitute Back to Find \(x\)
Now, we substitute \(y = 5\) back into one of the original equations. Using the second equation:
\[
-6x + 5 = 41
\]
Rearranging gives:
\[
-6x = 36 \quad \Rightarrow \quad x = -6
\]
Final Answer
The solution to the system of equations is:
\[
\boxed{(-6, 5)}
\]
