Question

step by step explanation​

Answer 1

Answer:

c) 3,1

Step-by-step explanation:

Given,

x=a and y=b

so, substituting values in equation x - y = 2

we get a - b = 2.....................(1)

and in x + y = 4

we get a + b = 4......................(2)

===============================

adding (1) + (2)

we get,

a - b = 2

+ a + b = 4

===============

2a = 6

⇒ a = 3

a + b = 4

3 + b = 4

b = 4 - 3

b = 1

⇒ a =3 and b = 1

so c is the right answer.
