Question

6x-4y=-12;8x-3y=-2.. solve the following simultaneous equations using Cramer rule​

Answer 1

Step-by-step explanation:

6x-4y=12

=x-4y=12/6

=x-4y=2

=x-y=2/4

=x-y=2

Answer 2

Answer:

In Cramer’s method, the equations are written as a1x + b1y = c1 & a2x + b2y = c2.

The value of determinant :

D = |a1 b1|

       |a2 b2|

D = a1b2 - a2b1

Dx = |c1 b1|

         |c2 b2|

Dx = c1b2 - c2b1

Dy = |a1 c1|

         |a2 c2|

Dy = a1c2 - a2c1

We find the value of x & y by using this formula:

x = Dx / D & y = Dy / D
