Answer:

Here,

given:

x=5 & y = -3 D= -5

Step-by-step explanation:

By Cramer's Rule,

x = Dx/D

we have,

5 = Dx/ -5

Dx = 5×5

Dx= 25

y = Dy/D

we have,

-3 = Dy/ -5

Dy = -3×5

Dy = -15

therefore, the value of Dx and Dy is 25 and -15 respectively.

Answer:

The value of Dx is -25 and that of Dy is 15.

Step-by-step explanation:

Given:

x = 5, y = -3, D = -5

To find:

Dx =?

Dy =?

Solution:

We know that according to Cramer's rule,

x = Dx/D, y = Dy/D, and z = Dz/D

Substituting the given values, we get

x = Dx/D

5 = Dx/-5

Dx = 5×-5

Dx = -25

y = Dy/D

-3 = Dy/-5

Dy = -3×-5

Dy = 15

Therefore, the values of Dx and Dy using Cramer's rule is -25 and 15 respectively.
