$\displaystyle\bf\\\left \{ {{\dfrac{x}{3} -\dfrac{y}{2} =-4} \atop {\dfrac{x}{2} +\dfrac{y}{4}=-2 }} \right. \\\\\\\left \{ {{\dfrac{x}{3}\cdot 6 -\dfrac{y}{2}\cdot 6 =-4\cdot 6} \atop {\dfrac{x}{2} \cdot 4+\dfrac{y}{4}\cdot 4=-2\cdot 4 }} \right. \\\\\\-\left \{ {{2x-3y=-24} \atop {2x+y=-8}} \right.\\ ----------\\2x-3y-2x-y=-24-(-8)\\\\-4y=-24+8\\\\-4y=-16\\\\y=-16:(-4)\\\\\boxed{y=4}\\\\2x=-8-y=-8-4=-12\\\\x=-12:2\\\\\boxed{x=-6}\\\\\\Otvet \ : \ (-6 \ ; \ 4)$
