Question

add the following algebraic expression 7 x y + 5yz-3zx,4yz+9zx-4y and -3xy+5x-2xy​

Answer 1

Answer:

5xy + 9yz + 3zx + 5x - 4y

Step-by-step explanation:

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

Answer 2

Step-by-step explanation:

7xy + 5yz-3zx+4yz+9zx-4y-3xy+5x-2xy

7xy-3xy-2xy+5yz+4yz-3zx+9zx-4y+5x

4xy -2xy+5yz+4yz-3zx+9zx-4y+5x

2xy +5yz+4yz-3zx+9zx-4y+5x

2xy+9yz -3zx+9zx-4y+5x

2xy+9yz+6zx-4y+5x
