Question

ecuaciones lineales de 2 icognitas x+3y=6 5x-2y=13

Answer 1

Respuesta:

y = 1 x = 3

Explicación paso a paso:

-5(x + 3y = 6)

5x - 2y = 13

-----------------

- 5x - 15y = - 30

5x - 2y = 13

-----------------

- 17y = - 17

17y = 17

y = 17/17

y = 1

x + 3y = 6

x + 3(1) = 6

x + 3 = 6

x = 6 - 3

x = 3
