Answer 1

$\displaystyle\bf\\\left \{ {{\dfrac{x}{3} -\dfrac{y}{2} =8} \atop {\dfrac{3x}{8} +\dfrac{y}{4} =22}} \right. \\\\\\\left \{ {{\dfrac{x}{3} \cdot 6-\dfrac{y}{2} \cdot6=8\cdot 6} \atop {\dfrac{3x}{8} \cdot8+\dfrac{y}{4}\cdot8 =22\cdot 8}} \right. \\\\\\\left \{ {{2x-3y=48} \ |\cdot2\atop {3x+2y=176} \ |\cdot 3} \right. \\\\\\+\left \{ {{4x-6y=96} \atop {9x+6y=528}} \right. \\----------\\13x=624\\\\x=48\\\\2y=176-3x=176-3\cdot 48=176-144=32\\\\y=16\\\\Otvet:\ (48 \ ; \ 16)$
