Question

Which of the first 10 natural numbers is NOT a solution of 5x−1≠9 ?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find which of the first 10 natural numbers is not a solution to the inequality 5x - 1 ≠ 9, we need to solve for x and check each number.

5x - 1 ≠ 9
5x ≠ 10
x ≠ 2

Therefore, x cannot be 2. Checking the first 10 natural numbers:
- 1: 5(1) - 1 = 5 - 1 = 4 ≠ 9 (satisfies inequality)
- 2: Not a solution
- 3: 5(3) - 1 = 15 - 1 = 14 ≠ 9 (satisfies inequality)
- 4: 5(4) - 1 = 20 - 1 = 19 ≠ 9 (satisfies inequality)
- 5: 5(5) - 1 = 25 - 1 = 24 ≠ 9 (satisfies inequality)
- 6: 5(6) - 1 = 30 - 1 = 29 ≠ 9 (satisfies inequality)
- 7: 5(7) - 1 = 35 - 1 = 34 ≠ 9 (satisfies inequality)
- 8: 5(8) - 1 = 40 - 1 = 39 ≠ 9 (satisfies inequality)
- 9: 5(9) - 1 = 45 - 1 = 44 ≠ 9 (satisfies inequality)
- 10: 5(10) - 1 = 50 - 1 = 49 ≠ 9 (satisfies inequality)

Therefore, the number that is not a solution of the inequality is 2.
