Question

Kim is solving the absolute value inequality |2x - 1| + 3 < 6. |2x-1| + 3 -3 < 6 - 3. |2x - 1| < 3. -3 < 2x - 1 r 2x - 1 < 3. -2 < 2x or 2x < 4. -1 < x or x < 2 where did km go wrong? explain your reasoning. A. Kim should have isolated the absolute value before writing the compund inequality. B. Kim should have used -3 > 2x -1 rather then -3 < 2x - 1. C. Kim should have used and instead of or in her compund inequality. D. kim should have reversed the ineqality symbol when solving 2x > -2

Answer 1

Everything looks legit in the solving part, it's just the statement of the solutions.

Answer 2

Try graphing the solutions.
