To determine the number of solutions for the system of equations given, we first need to rewrite the equations clearly based on the information provided.
1. The first equation appears to be:
\[
y = -\frac{1}{2}x + 4
\]
2. The second equation can be rewritten as:
\[
x + 2y = -8
\]
Now, we can solve this system to see how many solutions it has.
### Step 1: Substitute \( y \) from the first equation into the second equation
Substituting \( y \) from the first equation into the second equation:
\[
x + 2\left(-\frac{1}{2}x + 4\right) = -8
\]
### Step 2: Simplify the equation
Distributing \( 2 \) in the second equation gives:
\[
x - x + 8 = -8
\]
This simplifies to:
\[
8 = -8
\]
### Step 3: Analyze the result
The equation \( 8 = -8 \) is a contradiction, which tells us that the system of equations does not have any solutions.
### Conclusion
The answer is **no solution**.
