б) { 6x - y = -6, y + 2x² = 2.

1. Express y from the first equation: y = 6x + 6.
2. Substitute y into the second equation: (6x + 6) + 2x² = 2.
3. Solve the quadratic equation: 2x² + 6x + 4 = 0, which simplifies to x² + 3x + 2 = 0. Factoring gives (x+1)(x+2) = 0, so x₁ = -1 and x₂ = -2.
4. Find the corresponding y values: y₁ = 6(-1) + 6 = 0, y₂ = 6(-2) + 6 = -6.
Answer: (-1; 0), (-2; -6).
