Answer 1

Answer:

b) 5,2 is the correct answer please follow me

Answer 2

Step-by-step explanation:

Since, x - y = 3. ----------- (1)

x + y = 7. ----------- (2)

Now, by adding equation (1) & (2), we get

2x = 10

x = 5

Now, putting x = 5 in equation (2), we get

y = 7

Therefore, p = x = 5

q = y = 7
