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
Explanation
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.
