Question

for simultaneous equation in x and y,if Dx=27,Dy=9 and D=3 then what is value of y​

Answer 1

Answer:

x=3,y=3

Step-by-step explanation:

y=Dy/D

=9/3

y=3

x=Dx/D

=27/9

x=3

Answer 2

The value of y = 3

Step-by-step explanation:

We have,

Dx = 27,Dy = 9 and D = 3

To find, the value of y = ?

∴ Dx = 27

Put D = 3, we get

⇒$3\times x = 27$

⇒ $x = \dfrac{27}{3}=9$

⇒ x = 9

Also,

Dy = 9

⇒ $3\times y = 9$

⇒ y = 3

Hence, the value of y = 3
