To determine the number of solutions to the given system of linear equations:
1. **y = x + 5**
2. **y = -x + 5**
Let's analyze the two equations.
First, we can set the two equations equal to each other to find any points of intersection:
\[
x + 5 = -x + 5
\]
Now, add \(x\) to both sides:
\[
x + x + 5 = 5
\]
This simplifies to:
\[
2x + 5 = 5
\]
Next, subtract 5 from both sides:
\[
2x = 0
\]
Now, divide both sides by 2:
\[
x = 0
\]
Now that we have \(x\), we can substitute \(x = 0\) back into either equation to find the corresponding \(y\):
Using the first equation:
\[
y = 0 + 5 = 5
\]
So the solution to the system of equations is \( (0, 5) \).
Since we found one unique solution where both lines intersect, the answer is:
**1**
