x + y = 5 and x - y = 3 are two simultaneous linear equations, and they have only one solution?
- (4,1)
- (1,4)
- (2,3)
- None of these
Explanation
Let's solve the equations:
1. x + y = 5
2. x - y = 3
Add both equations:
2x = 8
x = 4
Now, substitute x = 4 in equation (1):
4 + y = 5
y = 1
The solution is (4, 1).
