Question

On the set of natural numbers the relation R defined by xRy if x+2y=1

Answer 1

Answer:

x = 1 & y = 0

Step-by-step explanation:

On the set of natural numbers the relation R defined by xRy if x+2y=1

x + 2y = 1

x & y are natural number

=> x ≤ 1  => x = 0 & 1

& 2y ≤ 1

=> y ≤ 1/2

=> y = 0    

for y = 0

x + 0 = 1

=> x = 1

x = 1 & y = 0  is the only solution
