Question

One more than 5 times a number is less than or equal to 10. Find all such numbers.

Answer 1

All numbers less than or equal to 9/5.

Explanation:

If the number is n, then

5n + 1 ≤ 10

5n ≤ 10 - 1

5n ≤ 9

n ≤ 9/5.

Answer 2

let the number be x
Form the equation : 5x + 1 ≤ 10
5x ≤ 10-1
5x ≤ 9
X ≤ 9/5
so X can be 9/5 or any values smaller than that.

hope this helps :)
