The document discusses linear inequalities with one variable. It provides examples of inequalities such as 2x - 1 > 3 and 2x - 3 > 4x + 5. It then shows how to determine the solution set of each inequality by manipulating and solving the inequalities. Finally, it provides three practice problems for finding the solution set of additional inequalities.

THE EXAMPLE 2X - 1 > 3 X 8 > 15
Determine the set of solution of the inequality 2x - 1 > 3. If x is variable of { -1, 0, 2, 4, 5, 9, 11} 2x 1 > 3 2x 1 +1 > 3 + 1 2x + 0 > 3 + 1 2x > 4 2x > 4 2 2 x > 2 The solution set of 2x 3 > 4x + 5 is { 4, 5 , 9 ,11 }
Determine the set of solution of the inequality 2x 3 > 4x + 5 If x is variable of { -8 , -7 , -6 , , 6 } SOLUTION 2x 3 > 4x + 5 2x 3 +3 > 4x + 5 +3 2x > 4x + 8 2x 4x > 4x 4x +8 - 2x > 8 - 2x < 8 -2 -2 x < - 4 The solution set of 2x 3 > 4x + 5 is { -8 , -7 , -6 , -5 }
Practice Find the solution set of the following inequalities: 1. y + 2 > 6 , y { 1 , 3 , 5 , 7 , 9 } 2. 2x 3 < 7 , x is prime numbers 3. z + 4 > 4z 5 , z is whole numbers
