Question

Madeline solved the inequality 3x + 7 ≤ 8x - 3 and her solution is x = 2.

Madeline is incorrect. Explain why she is incorrect. *

Answer 1

In her answer she has an equality, x=2. Emphasis on equal. However, in the original inequality it's not a equal sign. x=2 is true, just not the complete the answer.

Answer should be x is greater than or equal to 2.

Hopefully that makes sense.
