Question

X-1=2-y/3
1-y=-1-x/2

Answer 1

$x-1=2-\frac{y}{3}=>x+\frac{y}{3}=3\\\\1-y=-1-\frac{x}{2}=>\frac{x}{2}-y=-2 \\\\Despejamos-x-de-la-primer-ecucacion:\\\\x=3-\frac{y}{3}\\\\Sustituimos-x-en-la-segunda-ecuacion:\\\\\frac{3-\frac{y}{3} }{2}-y=-2\\\\\frac{\frac{9-y}{3} }{\frac{2}{1} } -y=-2\\\\\frac{9-y}{6}-\frac{y}{1} =-2\\\\\frac{9-y-6y}{6}=-2\\\\9-7y=-12\\\\-7y=-12-9\\\\-7y=-21\\\\y=3\\\\Sustituimos-y-en-la-primer-ecuacion:\\\\x+\frac{3}{3}=3\\\\x+1=3\\\\x=3-1\\\\x=2$
