Question

what should be added to 16x3y2 + 8xy to get 13y+8x3y2?​

Answer 1

Answer:

13y - 8x3y2 - 8xy should be added.

Step-by-step explanation:

let the number to be added be 'a'

then the process would be;

(16x3y2 + 8xy) + a = 13y+ 8x3y2

or, a = 13y + 8x3y2 - 16x3y2 - 8xy

or, a = 13y - 8x3y2 - 8xy

therefore, 13y - 8x3y2 - 8xy should be added.
