1) 4(x + 2) - 3(5 - x) - x - 3 = 4 * x + 4 * 2 - 3 * 5 + 3 * x - x - 3 = 4x + 8 - 15 + 3x - x - 3 = 4x + 3x - x + 8 - 15 - 3 = x(4 + 3 - 1) - 10 = 6x - 10;

2) 3(x + 3) - 4(3 - x) - (4 + 3)x - 3 = 3 * x + 3 * 3 - 4 * 3 + 4 * x - 4 * x - 3 * x - 3 = 3x + 9 - 12 + 4x - 4x - 3x - 3 = 3x + 4x - 4x - 3x + 9 - 12 - 3 = -6;

3) 5(x + 4) - (5 - x) - x - 3 = 5 * x + 5 * 4 - 5 + x - x - 3 = 5x + 20 - 5 + x - x - 3 = 5x + x - x + 20 - 5 - 3 = 5x + 12;

4) 4(x + 1) - 5(5 - x) - (5 + 4)x - 1 = 4 * x + 4 * 1 - 5 * 5 + 5 * x - 5 * x - 4 * x - 1 = 4x + 4 - 25 + 5x - 5x - 4x - 1 = 4x - 4x + 5x - 5x + 4 - 25 - 1 = - 22.
