To solve the system of linear equations given by \( y = 3x - 7 \) and \( y = 3x + 1 \), we need to find the values of \( x \) and \( y \) that satisfy both equations simultaneously. Since both equations have the same slope but different y-intercepts, they are parallel lines and do not intersect. Therefore, there is no solution to this system of equations.
Step 1: Analyze the System of Equations
The given system of equations is:
\[
\begin{align_}
y &= 3x - 7 \\
y &= 3x + 1
\end{align_}
\]
Both equations have the same slope of 3, indicating that the lines are parallel.
Step 2: Determine the Intersection
Since the lines are parallel, they do not intersect. Parallel lines with different y-intercepts do not have any common solution.
Final Answer
The system of equations has no solution. The lines are parallel and do not intersect. Therefore, the solution set is \(\boxed{\text{No Solution}}\).
