Question

If number of possible ordered
pairs (x,y) (where xand y are
integers) which satisfy
xy - 2x - y - 4 = 0 is 1, then
2X+1
equals
7​

Answer 1

Answer:

x=3

y=5

I think this is the correct answer

Answer 2

The possible ordered pair (x,y) is (3,5)

Step-by-step explanation:

Given,

Equation is xy-2x-y-4 = 0

Condition is 2x +1 = 7

∴ 2x = 7 - 1

2x = 6

x = 3

Now substituting the value of x in the given equation,

(3)y - 2(3) - y - 4 = 0

3y - 6 - y - 4 = 0

3y - y - 6 - 4 = 0

2y - 10 = 0

2y = 10

∴ y = 5

So the ordered pair is (3,5).
