Math Problem Statement

-2x+1 greater than -11

Solution

To solve the inequality:

2x+1>11-2x + 1 > -11

Step-by-Step Solution

  1. Subtract 1 from both sides to isolate the term with xx: 2x>111-2x > -11 - 1 2x>12-2x > -12

  2. Divide both sides by -2 to solve for xx, remembering to reverse the inequality sign when dividing by a negative number: x<122x < \frac{-12}{-2} x<6x < 6

Final Answer:

x<6x < 6
