Solving Inequalities

Solving double-ended inequalities

Listing Integers List all the integers which are solutions to the above inequality So, x is greater than 3 but less than 6. The only integers which fulfil this condition are: 4 and 5.

Listing integers Integers are: 5, 6, 7, 8, 9 Integers are: -1, 0 1 Integers are: -1, 0 1, 2, 3, 4, 5
