Step-by-step explanation:
We need to add horizontally.
1. 7x + 3y – 4x – 2y = 3x + y
2. 3a – 2b + c + 3 + a + 3b – 20 – 4 = 4a + b + c – 21
3. a + 2ab + b + a^2 – 2ab + b = a + a^2 + b
4. xy – yz + 2 + 2yz + xy – 7 + 3xy + 3yz + 3 = 5xy + 4yz – 2
5. 3pq + 2pr – 4qr -pq + 2qr + pr + 4pq – 3pr + 2qr = 6pq
