Question

D) Subtract:
1) 4x - 7xy + 3y + 12 from 12x - 9xy + 5y - 4​

Answer 1

12x - 9xy + 5y - 4 -(4x - 7xy + 3y - 12)

12x - 9xy + 5y - 4 - 4x + 7xy - 3y + 12

8x - 2xy + 2y - 8

Answer 2

Answer:

To subtract (4x - 7xy + 3y + 12) from (12x - 9xy + 5y - 4), we can simply subtract each term separately.

So,

(12x - 9xy + 5y - 4) - (4x - 7xy + 3y + 12)

= (12x - 4x) - (9xy + 7xy) + (5y - 3y) - (4 + 12)

= 8x - 16xy + 2y - 16

Therefore, the result of subtracting (4x - 7xy + 3y + 12) from (12x - 9xy + 5y - 4) is 8x - 16xy + 2y - 16.
