Question

5x-6y=9 4x+3y=13 metodo de reduccion

Answer 1

hola amig@ agi esta la respuesta espero q entiendas . saludos

Answer 2

1) 5x - 6y = 9        (3)
2) 4x + 3y = 13     (6)

15x - 18y = 27
24x + 18y = 78
----------------------
39x + 0y = 105

39x = 105
x = 105/39
x = 35/13

Reemplazo x en ecuación 2
4x + 3y = 13  
4 (35/13) + 3y = 13
140/13 + 3y = 13
3y = 13 - 140/13
3y = (13 * 13 - 140)/13
3y = (169 - 140)/13
3y = 29/13
y = 29/13/3/1
y = 29/39


x = 35/13
y = 29/39
