Question

what must be subtracted from 5 x minus 8 Y + 2 Z to get 3x-2y-5z​

Answer 1

5x-8y+2z - ?=3x-2y-5z

? = 5x-8y+2z - 3x-2y-5z

?=2x-6y+7z

therefore '2x-6y+7z' must be subtracted from 5x-8y+2z to get 3x-2y-5z.

Answer 2

Answer:

The answer is 2x+6y+7z.

Step-by-step explanation:

Let what must be subtracted a.

5x-8y+2z-a=3x-2y-5z

taking everything in the right to left side and (a) to the right of the equation,

5x-3x-8y+2y+2z+5z=a

2x+6y+7z=a.

So, 2x+6y+7z must be subtracted from 5x-8y+2z to get 3x-2y-5y.
