Question

Q. 5 solve
1) Form the simultaneous linear equation using the determinants.
D-| 4 -3 2 5|
Dx =| 5 -3 9 5| DY=| 4 5 2 9|​

Answer 1

Answer:

x= 2 y= 1 d= 26

Step-by-step explanation:

d = 4×5 - (-3)×2

d= 20 - (-6)

d=26

dx =5×5 -(-3)×9

dx=25 -(-27)

dx=-52

dy= 4×9 - 5×2

dy = 36 - 10

dy = 26

x = dx/d

-52/26

x =-2

y= dy/d

26/26

y =1

(x,y) (-2,1)
