Answer 2

$Let \:A = -3x+7y-16 \: and \: B = 4a - 3b + 20$

$Let \: 'm' \: should \:be \: added \: to \: A \: to$

$get \: B$

$\implies A + m = B$

$\implies m = B - A$

$\implies m = (4a - 3b + 20) - (-3x+7y-16)$

$\implies m = 4a - 3b + 20 + 3x - 7y + 16$

$\implies m = 4a - 3b + 3x - 7y + 36$

Therefore.,

$\green { (4a - 3b + 3x - 7y + 36)} \: should \: be$

$added \:to\: (-3x+7y-16) \:to \: get \: (4a-3b+20)$
