Answer 1

Respuesta:

$\left \{ {{\frac{x+y}{5} =\frac{x-y}{3} } \atop {\frac{x}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {{\frac{3x+3y}{5} =x-y } \atop {\frac{x}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {3x+3y=5x-5y } \atop {\frac{x}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {8y=2x } \atop {\frac{x}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {4y=x } \atop {\frac{x}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {4y=x } \atop {\frac{4y}{6}+\frac{y-2}{4} =3}} \right.$

$\left \{ {4y=x } \atop {\frac{16y}{24}+\frac{6y-12}{24} =3}} \right.$

$\left \{ {4y=x } \atop {\frac{16y+6y-12}{24} =3}} \right.$

$\left \{ {4y=x } \atop 16y+6y-12} =72}} \right.$

$\left \{ {4y=x } \atop 22y} =72+12}} \right.$

$\left \{ {4y=x } \atop 22y} =84}} \right.$

$\left \{ {4y=x } \atop y} =3,81}} \right.$

$\left \{ {4*3,81=x } \atop y} =3,81}} \right.$

$\left \{ {15,27=x } \atop y} =3,81}} \right.$
