Given algebraic expressions :
- 7xy + 5yz - 3zx
- 4yz + 9zx - 4y
- - 3xz + 5x - 2xy
⇒ (7xy + 5yz - 3zx) + (4yz + 9zx - 4y) + (- 3xz + 5x - 2xy)
⇒ 7xy + 5yz - 3zx + 4yz + 9zx - 4y - 3xz + 5x - 2xy
⇒ 7xy - 2xy + 5yz + 4yz - 3zx + 9zx - 3xz + 5x - 4y
⇒ (7 - 2)xy + (5 + 4)yz + (- 3 + 9 - 3)zx + 5x - 4y
⇒ (5)xy + (9)yz + (- 6 + 9)zx + 5x - 4y
⇒ (5)xy + (9)yz + (3)zx + 5x - 4y
⇒ 5xy + 9yz + 3zx + 5x - 4y
