x + y = 5 and x - y = 3 are two simultaneous linear equations, and they have only one solution?

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).
