Question

5) R is a relation on N given by R{(x, y)/4x + 3y = 20) which of the following belongs to R?

a) (5,0)

b) (-4,12)

c) (2,4)

d) (3,4).​

Answer 1

Answer:

4x + 3y = 20

x = 5, y = 0

x = 3,

12 + 3y = 20

3y = 8

y = 8 / 3

x = 2, 8 + 3y = 20

3y = 12

y = 4

x = (2, 4) is the only ordered pair that satisfies the given relation.
