3 3 Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Usually youll see it when you learn about solving inequalities because for some reason saying x 3 isnt good enough so instead theyll want you to phrase the answer as the solution set is x x is a real number and x 3. Intersection of two given sets is the largest set which contains all the elements that are common to both the sets.
The solution set of an or compound inequality is written in the same way but with the word or used instead of and.
We can solve absolute value inequalities much like we solved absolute value equations. Usually youll see it when you learn about solving inequalities because for some reason saying x 3 isnt good enough so instead theyll want you to phrase the answer as the solution set is x x is a real number and x 3. Solve linear equations and inequalities in one variable including equations with coefficients represented by letters. Another commonly used and arguably.
