The inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.

<h3>What is inequality?</h3>

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let's assume that the number would be x

The sum of a number and -4 is at least 8

According to the given question, translate the phrase into an algebraic form :

x - 4 ≥ 8

Add 4 both sides of the above inequality,

x - 4 + 4 ≥ 8 + 4

x ≥ 12

Therefore, the inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.
