Question

resuelve por el método de igualación:
x+3y= -4
x-2y= 6

Answer 1

Respuesta:

0

Explicación paso a paso:

  x = 3y - 9

// Plug this in for variable  x  in equation [1]

  [1]    (3y-9) + 2y = 6

  [1]    5y = 15

// Solve equation [1] for the variable  y  

  [1]    5y = 15  

  [1]    y = 3  

// By now we know this much :

   x = 3y-9

   y = 3

// Use the  y  value to solve for  x  

   x = 3(3)-9 = 0
