Which of the first 10 natural numbers is not a solution to 5x - 1 = 9?

Answer 1

To find which of the first 10 natural numbers is not a solution to the equation 5x - 1 = 9, we can substitute each of the numbers into the equation and check if it satisfies the equation.

Substituting x = 1 into the equation:
5(1) - 1 = 5 - 1 = 4
Since 4 is not equal to 9, x = 1 is not a solution.

Substituting x = 2 into the equation:
5(2) - 1 = 10 - 1 = 9
Since 9 is equal to 9, x = 2 is a solution.

Substituting x = 3 into the equation:
5(3) - 1 = 15 - 1 = 14
Since 14 is not equal to 9, x = 3 is not a solution.

Substituting x = 4 into the equation:
5(4) - 1 = 20 - 1 = 19
Since 19 is not equal to 9, x = 4 is not a solution.

Substituting x = 5 into the equation:
5(5) - 1 = 25 - 1 = 24
Since 24 is not equal to 9, x = 5 is not a solution.

Substituting x = 6 into the equation:
5(6) - 1 = 30 - 1 = 29
Since 29 is not equal to 9, x = 6 is not a solution.

Substituting x = 7 into the equation:
5(7) - 1 = 35 - 1 = 34
Since 34 is not equal to 9, x = 7 is not a solution.

Substituting x = 8 into the equation:
5(8) - 1 = 40 - 1 = 39
Since 39 is not equal to 9, x = 8 is not a solution.

Substituting x = 9 into the equation:
5(9) - 1 = 45 - 1 = 44
Since 44 is not equal to 9, x = 9 is not a solution.

Substituting x = 10 into the equation:
5(10) - 1 = 50 - 1 = 49
Since 49 is not equal to 9, x = 10 is not a solution.

Therefore, none of the first 10 natural numbers satisfies the equation 5x - 1 = 9.

Answer 2

you must pick one

Answer 3

Apologies for the confusion. Based on the given equation 5x - 1 = 9, the solution we are looking for is the natural number that satisfies this equation.

By simplifying the equation, we have:
5x - 1 = 9
Adding 1 to both sides:
5x = 10
Dividing both sides by 5:
x = 2

So, the solution to the equation 5x - 1 = 9 is x = 2.

Therefore, the natural number that is not a solution to the equation among the first 10 natural numbers is x = 1.
