Question

for some simultaneous equations given below x=?, y=? . equation = D=5, D x = 25 , D y = 10 .​

Answer 1

S O L U T I O N :

Given :

• D = 5 , Dx = 25 , Dy = 10

To Find :

• The values of x and y.

Explanation :

According to the Cramer's rule,

x = Dx/D OR y = Dy/D

[ First solve for x ]

⟶ x = 25/5

⟶ x = 5

[ Now solve for y ]

⟶ y = 10/5

⟶ y = 2

Therefore,

The value of x and y is 5 and 2 respectively.
