{5x-4y=37
lo nesecito para horita :3 (｡・//ε//・｡)​

Answer 1

Respuesta:

x = 3/13 y = -233/26

Explicación paso a paso:

Método de reducción:

{4x+2y=-17(x5)

{5x-4y=37(x-4)

20x + 10y = -85

-20x + 16y = -148

26y = -233 => y = -233/26

4x + 2(-233/26) = -17

4x - 233/13 = -17

4x = -221/13 + 233/13 => 4x = 12/13

x = 12/13 x 1/4 => x = 3/13

Comprobación:

4(3/13) + 2(-233/26) = -17

12/13 - 233/13 = -17 => -221/13 = -17

-17 = -17

5(3/13) - 4(-233/26) = 37

15/13 + 466/13 = 37 => 481/13 = 37

37 = 37

RPTA: x = 3/13 y = -233/26
