Answer quickly. 1. solve by the linear combination method. 3x – 5y = 7 2x + 3y = 30 (3, –7) (9, 4) (3, 7) (–3, –7) 2. solve by the linear combination method. 2x + 3y = –17 5x + 2y = –4 (3, –1) (–2, 2) (–1, 3) (2, –7) 3. solve by the linear combination method. x + y = 50 0.05x + 0.06y = 2.8 (20, –50) (10, 30) (20, 30) (40, 60) 4. solve by the linear combination method. 8g – 5h = 7 4g + 10h = 1 (-3/4, -1/5) (-3/4, 1/5) (3/4, -1/5) (3/4, 1/5)
