Question

sistema de ecuaciones
5x+2y=1
-3x+3 Y=5​

Answer 1

Respuesta:

5x + 2y = 1

-3x+ 3y = 5

(3) 5x + 2y = 1

(-2)-3x+ 3y = 5

15x + 6y = 3

6x  - 6y = -10

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

21x =7

x = 7/21

x = 1/3

Reemplazamos para halar "y"

5x + 2y = 1

5(1/3) + 2y = 1

5/3 + 2y = 1

2y = 1 - 5/3

2y = (3 - 5) / 3

2y = -2/3

y = 2 (-2/3)

y = -4/3
