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
