1. 37 * a * 6 + 96 – 70 * 3 * a + 4 = 37a * 6 + 96 – 70 * 3a + 4 = 222a + 96 – 210 a + 4 = 12a + 100 = 4 * (3a + 25);
2.  2 * (8 + 12 * c) + (4 – c * 7) * 3 – 3 * c =  2 * (8 + 12c) + (4 – 7c) * 3 – 3c = 16 + 24c + 12 – 21c – 3c = 28;
3. 8 * (6 + k) + (3 * k - 3) * 4 – 7 = 8 * (6 + k) + (3k - 3) * 4 – 7 = 48 + 8k + 12k – 12 – 7 = 20k - 29;
4. 5 * (3 + p) + (5 * p - 1) * 6 – 9 = 15 + 5p + 30p – 6 – 9 = 35p.
