## To solve the problem, let's break it down step by step.

1. The problem states that a number is less than the sum of twice its opposite and five.

- Let's assume the unknown number is represented as x.

2. The term "opposite" refers to the same number with the opposite sign.

- So, the opposite of x would be -x.

3. According to the problem, the number x is less than the sum of twice its opposite (-2x) and five.

- This can be represented as: x < -2x + 5.

4. Now, let's solve the inequality to find the value of x.

- To get rid of the -2x on the right side of the inequality, we can add 2x to both sides, while keeping the direction of the inequality the same:

x + 2x < -2x + 5 + 2x.

Simplifying this, we get:

3x < 5.

5. Finally, to isolate x, we divide both sides of the inequality by 3, while keeping the direction of the inequality the same:

(3x)/3 < 5/3.

Simplifying this, we get:

x < 5/3.

Therefore, the solution to the problem is x < 5/3. This means that any number which is less than 5/3 will satisfy the given condition.
