x+y = 99, x-y = 9 ... 45.
- 54
- 56
- 57
- None of these
Explanation
We have two equations:
x + y = 99 ... (1)
x - y = 9 ... (2)
Add (1) and (2) to eliminate y:
2x = 108
Divide by 2:
x = 54
Now, substitute x into (1) to find y:
54 + y = 99
Subtract 54 from both sides:
y = 45
So, the values are x = 54 and y = 45.
