Question

2x + 3y = -3
5x +6y= 0

Answer 1

Respuesta:

x = 6   y = -5

Explicación paso a paso:

2x + 3y = -3..........(II)

5x +6y= 0.......(I)

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

5x +6y= 0

x = -6y/5

Reemplazamos en II

2(-6y)/5 + 3y = -3

-12y/5 + 3y = -3

(-12y + 15y)/5 = -3

3y = -15

y = -5

Hallamos "X"

2x + 3(-5) = -3

2x = 12

x = 6
