Question

What should be subtracted from x+2y-3z to get 3x-2y + z​

Answer 1

Answer:

-2x+4y-4z

Step-by-step explanation:

let the equation to be subtracted be "k

x+2y-3z-(k) = 3x-2y+z

x+2y-3z -(3x-2y+z) = k

x+2y-3z-3x+2y-z= k

-2x+4y -4z =k

verification:

x+2y-3z -(-2x+4y-4z) =3x-2y+z

x+ 2y-3z +2x-4y+4z =3x-2y+z

3x-2y+z = 3x-2y+z

LHS=RHS
