To solve the system of equations

  1. \( 5x + y = -3 \)
  2. \( -5x - y = 3 \)

we can use the method of substitution or elimination. Here, we'll use the elimination method.

First, let's add both equations together:

\[ (5x + y) + (-5x - y) = -3 + 3 \]

This simplifies to:

\[ 0 = 0 \]

Since we get a true statement (0 = 0), it indicates that the two equations represent the same line. Therefore, the system has infinitely many solutions.

To express the solution, we can solve for \( y \) in terms of \( x \) using the first equation:

\[ y = -3 - 5x \]

Thus, the solution can be expressed as:

\[ { (x, -3 - 5x) ; | ; x \in \mathbb{R} } \]

This means that for any real number \( x \), there is a corresponding \( y \) value that satisfies both equations.
