Question

1. For simultaneous equations in x and y, if Dx=25, Dy,=50, D=5,
then what is the value of x?


​

Answer 1

given d=5

therefore dx=25

x=25|5

=5

therefore value of x is 5

Answer 2

DX=25

Dy=50

D=5

This is given in question

formula use

I)DX/D

ii)Dy/D

explanation:

I) 25÷5=5

ii) 50÷5=10

This is final answer
