Question

if dx=-35 and d=-7 are the values of the determinants for certain simultaneous equations in x and y, find x​

Answer 1

Step-by-step explanation:

Solution:

Solution :Given, D=7,Dx=35 and Dy=42

Solution :Given, D=7,Dx=35 and Dy=42Now x=DDx=735=5

Solution :Given, D=7,Dx=35 and Dy=42Now x=DDx=735=5and y=DDy=742=6

Solution :Given, D=7,Dx=35 and Dy=42Now x=DDx=735=5and y=DDy=742=6∴ The value of x and y is 5 and 6.

Given, D=7,D

x

=35 and D

y

=42

Now x=

D

D

x

=

7

35

=5

and y=

D

D

y

=

7

42

=6

∴ The value of x and y is 5 and 6 respectively.
