Question

Solve 5x<24 when 1)X∈N, 2)X∈Z. in each case, represent the solution set on the number line.​

Answer 1

Given :  5x < 24  

To Find : Solve

x  ∈ N

X ∈ Z

Solution:

5x < 24  

=> x  < 24/5

=> x  <  4.8

x  ∈ N

=>   x  = { 1 , 2 , 3 , 4 }

5x < 24  

=> x  < 24/5

=> x  <  4.8

x  ∈ Z

=>   x  = {  -∞ , ..............., 2 , 3 , 4 }
