Question

1
6x-5y = - 9
Чx + 3y = 13​

Answer 1

1) 6x - 5y = - 9 (3)

2) 4x + 3y = 13 (5)

18x - 15y = - 27

20x + 15y = 65

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

38x + 0y = 38

38x = 38

x = 38/38

x = 1

Reemplazo x = 1 en 2.

4x + 3y = 13

4 (1) + 3y = 13

4 + 3y = 13

3y = 13 - 4

3y = 9

y = 9/3

y = 3

Solución :

x = 1

y = 3
