❥Answer࿐

4x - y - 8 = 0 \:  \:  \: 2x - 3y + 6 = 0

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
