Question

By translating the axes in the equation xy - x + 2y = 6 has changed to XY = c then c =

Answer 1

xy - x + 2y =6

Adding - 2 on both sides

xy - x + 2y -2 = 6 - 2

x (y-1)+2(y-1)= 4

(x+2) (y-1) = 4

This equation is of the form
(x - h) (y - k) = C (or ) XY = C

===> C = 4

I hope this answer help you

Answer 2

Answer:

We have

xy−x+2y=6

Now,

xy−x+2y=6

⇒xy−x+2y−6=0

⇒xy−x+2y−2=4

⇒x(y−1)+2(y−1)=4

⇒(x+2)(y−1)=4

This equation is the form of XY=C

Then,

C=4

Hence, this is the answer.
