To see which of the first 10 natural numbers is not a solution of 5x - 1 ≠ 9, we can substitute each number into the equation and check if the inequality is satisfied or not.
Let's start by substituting the number 1:
5(1) - 1 ≠ 9
4 ≠ 9
Since 4 is not equal to 9, the equation is satisfied. Therefore, 1 is NOT the solution.
Next, let's substitute the number 2:
5(2) - 1 ≠ 9
9 ≠ 9
This time, 9 is equal to 9, so the equation is not satisfied. Therefore, 2 is the solution.
Continuing this process, we find that the following numbers are also solutions: 3, 4, 5, 6, 7, 8, 9, and 10.
Therefore, the natural number NOT a solution of 5x - 1 ≠ 9 is 2.
