ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\therefore (4a-7ab+3b+12)$

$\sf\therefore (12a-9ab+5b-3)$

$\large\underline\bold{SOLUTION,}$

$\sf\therefore 12a-9ab+5b-3-4a-7ab+3b+12$

$\sf\implies 12a-4a-9ab-7ab+5b+3b-3+12$

$\sf\implies 8a-16ab+8b+9$

$\large{\boxed{\bf{\therefore 8a-16ab+8b+9}}}$

simplified,

$\sf\implies 8(1a-2ab+1b)+9$
