Question

$\left \{ {{x+3y=6} \atop {5x+2y=13}} \right.$

Answer 1

Respuesta:

y = 51/39; x = 27/13

Explicación paso a paso:

x + 3y = 6... (1)

5x + 2y = 13... (2)

3(2) - 2(1)

15x + 6y = 39

- 2x - 6y = - 12

→ 13x = 27; x = 27/13

Reemplazamos en (1)

x + 3y = 6

27/13 + 3y = 6

27 + 39y = 78

y = 51/39
