Question

For simultaneous equation in x and y if D = 28 ,Dx=-14, Dy=-21 then what is the value of y?​

Answer 1

Answer:

-3/4

Step-by-step explanation:

D=28 .....i

Dx=-14

28x=-14 (from equations i)

x=-1/2

Dy=-21

28y=-21 (from equations i)

y= -3/4

Answer 2

Answer:

-21/28 is y value

Step-by-step explanation:

given d=28

given dy=-21

so put d value in the dy equation

28*y=-21

taking 28 to other side hence it becomes denominator of -21

so y=-21/28
