Question

solve the following inequalities and graph the solution set :-
​

Answer 1

Answer :

x = 1 , 2 , 3 , 4 , 5

Solution :

• Given : 3 - 2x ≥ x - 12 , x € N
• To find : x = ?

We have ,

=> 3 - 2x ≥ x - 12 , x € N

=> -2x - x ≥ -12 - 3 , x € N

=> -3x ≥ -15 , x € N

=> 3x ≤ 15 , x € N

=> x ≤ 15/3 , x € N

=> x ≤ 5 , x € N

=> x = 1 , 2 , 3 , 4 , 5

Hence ,

x = 1 , 2 , 3 , 4 , 5
