Example: Solve 2(x+3) < 5 (x3). Solution: 2x+6 < 5x15. Add 6 to both sides, we get 2x + 6  6 < 5x  15 6 2x < 5x  21 Add 5x to both sides, we get 2x  5x < 5x 21 5x 3x < 21 Divide both sides by 3. 3x/3 > 21/3 x > 7 \ Any number > 7 is a solution.
Verification: Substituting x = 8 > 7 Directions: Solve the following inequality. Also write at least ten examples of your own.
