Answer 1

Step-by-step explanation:

bhai pta nhi yrr smjh hi nhi aa rha question

Answer 2

Step-by-step explanation:

N is a natural number

N = 1,2,3,4,5.........

given a,b belongs to N

if a = 1

2(1) + b =10

2 + b = 10

b = 10 - 2

b = 8

if a = 2

2(2) + b = 10

4 + b = 10

b = 10 - 4

b = 6

if a = 3

2(3) + b = 10

6 + b = 10

b = 10-6

b = 4

if a = 4

2(4) + b = 10

8 + b = 10

b = 10 - 8

b = 2

so

R = {(1,8),(2,6),(34),(4,2)}answer
