If 78.36 = 78.36xy then which of the following is correct?

x = 1 and y = 1

x = 0 and y = 0

x = 0 and y = 1

None of these

Given the equation:

78.36 = 78.36xy

Dividing both sides by 78.36:

1 = xy

The only option that satisfies xy = 1 is:

x = 1 and y = 1

Since 1 × 1 = 1.

The answer is x = 1 and y = 1.
