To determine which of the provided ordered pairs are solutions to the system of equations given by:
1. \( 3x - 5y = 15 \)
2. \( 2x - y = -4 \)
we can substitute each ordered pair into both equations and check for validity.
### Checking each ordered pair:
1. **For the ordered pair \((-5, -6)\)**:
- Substitute \(x = -5\) and \(y = -6\) into both equations.
\[
3(-5) - 5(-6) = -15 + 30 = 15 \quad \text{(First equation is satisfied)}
\]
\[
2(-5) - (-6) = -10 + 6 = -4 \quad \text{(Second equation is satisfied)}
\]
**Result**: This pair is a solution.
2. **For the ordered pair \((2, 8)\)**:
- Substitute \(x = 2\) and \(y = 8\):
\[
3(2) - 5(8) = 6 - 40 = -34 \quad \text{(Not satisfied)}
\]
**Result**: This pair is NOT a solution.
3. **For the ordered pair \((0, 3)\)**:
- Substitute \(x = 0\) and \(y = 3\):
\[
3(0) - 5(3) = -15 \quad \text{(Not satisfied)}
\]
**Result**: This pair is NOT a solution.
4. **For the ordered pair \((-6, -11)\)**:
- Substitute \(x = -6\) and \(y = -11\):
\[
3(-6) - 5(-11) = -18 + 55 = 37 \quad \text{(Not satisfied)}
\]
**Result**: This pair is NOT a solution.
### Conclusion:
The only ordered pair that is a solution to the system of equations is \((-5, -6)\).
