Question

3x - 4y= -10 5x + 8 y = -2 es

Answer 1

Hola !! ^^

=> Resolviendo :

3x - 4y = - 10

5x + 8y = - 2

Multiplicamos por 2, la primera ecuación :

6x - 8y = - 20

5x + 8y = -2

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

11x = -22

x = - 22/11

x = - 2

=> Hallamos "y" :

3x + 10 = 4y

3 (-2) + 10 = 4y

10-6 = 4y

4 = 4y

4/4 = y

1=y
