To analyze the system of equations:

1. \( y = -x + 3 \)
2. \( x + y = 8 \)

We can rewrite the second equation in slope-intercept form (y = mx + b):

Starting from \( x + y = 8 \):
- Subtract \( x \) from both sides:
\[ y = -x + 8 \]

Now we can compare the two equations:
1. \( y = -x + 3 \) (slope = -1, y-intercept = 3)
2. \( y = -x + 8 \) (slope = -1, y-intercept = 8)

Since both lines have the same slope (-1) but different y-intercepts, they are parallel lines. Parallel lines will never intersect, which means there is no solution to the system of equations.

Thus, the statement is **true**, and the correct response is:

"The statement is true, because the lines are parallel."
