Question

what should be added to x+2y-3z to get 3x-2y+z​

Answer 1

Answer:

we have to add 2x-4y+4z to get 3x-2y+z

Answer 2

Answer:

(2x - 4y + 4z) should be added to (x + 2y - 3z) to get (3x - 2y +z).

Step-by-step explanation:

Explanation:

Given, x + 2y - 3z

And according to the question we need to convert (x + 2y - 3z) into

(3x-  2y +z).

Therefore, if we add (2x -4y + 4z) we get,

⇒(x + 2y - 3z) + (2x - 4y + 4z)

⇒(x + 2y - 3z +2x - 4y + 4z)

⇒(3x - 2y+ z )

Here we proved that on adding (2x - 4y + 4z)to (x + 2y - 3z) we get

(3x - 2y + z).

Final answer:

Hence,  (2x - 4y + 4z) should be added to (x + 2y - 3z) to get (3x - 2y +z).
