❥Answer࿐
Step-by-step explanation:
4x -y -8 = 0
4x -y = 8--------(1)
2x -3y +6 = 0
2x -3y = -6--------(2)
D = / a1 b1/
/ a2 b2/
D = /4 1 /
/2 3 /
D = 4× 3 - 1× 2
D = 12 - 2
D = 10
Dy = / c1 b1 /
/c2 b2/
Dy = / 8 1/
/ -6 -3 /
Dy = 8 × -3 - (-6 × 1)
Dy = -24 - (-6)
Dy = -30
Dx = /a1 c1/
/ a2 c2/
Dy = / 4 8 /
/ 2 -6/
Dy = 4× -6 -(2× 8)
Dy = -24 -16
Dy = -40
D = 10 ,Dy = -30, Dy = -40
kramers rule,
X = Dx/d
x= -40/10
x = -4
Y = Dy /d
Y = -30/10
y = -3
