$\mathsf{a)\:x.(-4) = 12\iff x = \dfrac{12}{-4} = -3}$

$\mathsf{b)\:(-18):x = 9\iff x = \dfrac{-18}{9} = -2}$

$\mathsf{c)\:-63:x = -1\iff x = \dfrac{-63}{-1} = 63}$

$\mathsf{d)\:-40\:.\:x = 120\iff x = \dfrac{120}{-40} = -3}$

$\mathsf{e)\:x:(-4) = -25 \iff x = (-4).(-25) = 100}$

$\mathsf{f)\:x:(-10) = 200 \iff x = \dfrac{200}{-10} = -20}$

$\mathsf{g)\:x:(-4) = 0\iff x = \dfrac{0}{-4} = 0}$

$\mathsf{g)\:x\:.\:(-1) = 1\iff x = \dfrac{1}{-1} = -1}$
