$\huge\tt\bold{\red{Remember:}}$

whenever Question say substract from :-you have to substract from value which is after from .

$\bold{⟹12a - 9ab + 5b - 3 - (4a - 7 ab + 3b + 12)}$

NOW , separate like terms one side and then substract to make it easy calculation

$\bold{⟹12a - 9ab + 5b - 3 - 4a + 7ab - 3b - 12}$

$\bold{⟹12a - 4a - 9ab + 7ab + 5b - 3b - 3 - 12}$

$⟹\bold{8a - 2ab + 2b - 15}$

$⟹\bold{\green{\boxed{\bold{8a - 2b(a - 1) - 15}}}}$
