Question

solve by Cramer's rule
6x - 4 y = -12 ; 8x - Зу = -2​

Answer 1

Answer:

6x-4y= -12; 8x-3y= -2

6x-4y=-12

x = 1/6( 4 y - 12)

x = 2/3y -2

8 ( 2/3 y - 2) - 3 y = - 2

16

____________

3 y - 16 - 3y = - 2

7 y - 16 = - 2

3

7/3 y = 14

y = 6

x = 2/3 × 6 - 2

x = 4-2

x = 2

( x = 2 , y = 6)
