Question

What are all possible values of x if
10
x
+
5
≥
25
?

Answer 1

x can be all real positive numbers besides 1.

Explanation:

10x + 5 ≥ 25

10x ≥ 25 - 5

10x ≥ 20

10x/10 ≥ 20/10

x ≥ 2

Since x is larger than or equal to 2, it can be any number besides 1 and all negative numbers. It can still be 2 because it says larger than or equal to.

Ans: x can be all real positive numbers besides 1.
