Question
The solution set of |2x + 3| > 5 is
Solution
To solve the inequality |2x + 3| > 5, we need to consider two cases because of the absolute value.
Case 1: 2x + 3 > 5 Subtract 3 from both sides: 2x > 2 Divide both sides by 2: x > 1
Case 2: -(2x + 3) > 5 Distribute the negative sign: -2x - 3 > 5 Add 3 to both sides: -2x > 8 Divide both sides by -2 (remember to flip the inequality sign because we're dividing by a negative number): x < -4
So the solution set for the inequality |2x + 3| > 5 is x < -4 and x > 1.
