Answer :

(a)


Let x = 1,


As, x + y = 7


1 + y = 7


y = 6


Hence, solution is x = 1 and y = 6.


(b)


Let x = 2,


As, x + y = 7


2 + y = 7


y = 5


Hence, solution is x = 2 and y = 5.


(c)


Let x = 3,


As, x + y = 7


3 + y = 7


y = 4


Hence, solution is x = 3 and y = 4.


(d)


Let x = 4,


As, x + y = 7


4 + y = 7


y = 3


Hence, solution is x = 4 and y = 3.


(e)


Let x = 5,


As, x + y = 7


5 + y = 7


y = 2


Hence, solution is x = 5 and y = 2.
