Solution using elimination:
- Subtract the second equation from the first equation to eliminate x: \( (x - 2y) - (x - 3y) = -8 - (-8) \).
- Simplify and solve for y: \( x - 2y - x + 3y = -8 + 8 \) => \( y = 0 \).
- Substitute the value of y back into either original equation. Using the first equation: \( x - 2(0) = -8 \).
- Solve for x: \( x - 0 = -8 \) => \( x = -8 \).
Answer: x = -8, y = 0
