Question

Plz ans fastly....plz If xy=192 x-y=4 And x+y=28 What is the value of x and y?

Answer 1

Step-by-step explanation:

x-y=4...........(first eq.)

x+y=28.........(second eq.)

From the first eq.

x-y=4

y=x-4.....(1)

Substituting the value of (1) in the second eq.

x+x-4=28

2x-4=28

2x=28+4

2x=32

x=16

Now let's find the original value of y from (1)

y=x-4

y=16-4

y=12.

Value of x=16

Value of y=12.

[No need of xy=192. It is only there to make you confuse.]

Hope it helps.
