Solve the following equations (1) 2x + 3Y + 4 = 05x + 6y + 7 = 0 (2) x2 + Y3 = 24 (x − y − 1) = 3 (1 − y) − 2

Solve the following equations (1) 2x + 3Y + 4 = 05x + 6y + 7 = 0 (2) x2 + Y3 = 24 (x − y − 1) = 3 (1 − y) − 2

(1) 2X + 3Y + 4 = 0, 1 5x + 6y + 7 = 0, 2, 1 × 2 - 2: x = - 1, solution: x = 1, substituting x = 1 into 1: 2 + 3Y + 4 = 0, solution: y = - 2, then the solution of the system of equations is x = 1y = - 2; (2) the system of equations is sorted out: 3x + 2Y = 12, 1 4x − y = 5, 2, 1 + 2 × 2: 11x = 22, solution: x = 2, x = 2
