Question

4) For simultaneous equations, in Variables x and y, if D = 4, Dx = 2 and Dy = 8. Find the value of y.​

Answer 1

Answer:

d=4 so

x=4/2=2

y=8/2

Answer 2

Answer:

The value of y is 2.

Step-by-step explanation:

In context to the question asked,

We have to find the value of y,

As per the data given in the question,

It is given that,

D = 4,

Dx = 2,

Dy = 8

For solving this we have to use Cramer's rule,

Cramer’s rule is one of the important methods applied to solve a system of equations.

For calculating the value of y,

The formula to be used:

$=> y = \frac{Dy}{D}$

Substitute the given values in the above formula,

$=> y = \frac{8}{4}$

Divide 8 by 4, we get

$=> y = 2$

Hence, the value of y is 2.
