Send the 4 th one by crammer's rule​

Answer 1

Answer:

hy

Step-by-step explanation:

Final Answer:  x= 2 , y = 6  

Solution :  Cramer,s Rule :Most awesome Method to solve linear Equations  

Steps:

1)  

We have,

                   6x-4y=-12  

                   8x-3y = -2  

2) Coeffcient Matrix :  

Determinant ,D = (6*-3)-(-4*8)=-18+32=14  

X-Matrix :  

Determinant,Dx = (-12*-3)-(-2*-4) =36-8=28    

Y-Matrix :  

Determinant ,Dy = (6*-2)-(8*-12) = -12+96=84  

3) Now,  

   By  Cramer's Rule,

  x= Dx/d=28/14

=2

   y=Dy/d=84/14

=6

 Hence ,

x=2

y=6
