To solve the system of equations:
- \(-x - 4y = 2\)
- \(x + 4y = -2\)
We can first rewrite the first equation and align it with the second equation:
\(-x - 4y = 2\) can be rewritten as \(x + 4y = -2\).
Notice that both equations can be simplified to the same single equation:
\[ x + 4y = -2 \]
Since both equations are the same, this means there are infinitely many solutions that satisfy this equation.
Thus, the answer is:
The system had infinitely many solutions.
