Answer 2

1. (2x + 3) + (3x - 4) = 2x + 3x + 3 - 4 = 5x - 1
2. (3x - 4) + (2x + 3) = 3x + 2x - 4 + 3 = 5x - 1
3. (x - y) + (4x - 2y) = x + 4x - y - 2y = 5x - 3y
4. (4x - 2y) + (x - y) = 4x + x - 2y - y = 5x - 3y
5. (a + 3b) + (3a - b) = a + 3a + 3b - b = 4a + 2b
6. (3a - 6) + (a + 3b) = 3a + a - 6 + 3b = 4a - 6 + 3b
