Final answer:
To determine if a number is a solution to an inequality, substitute the value of the number into the inequality and check if it satisfies the inequality.
Step-by-step explanation:
In order to determine if a number is a solution to an inequality, you need to substitute the value of the number into the inequality and check if it satisfies the inequality. If the inequality is true when the number is substituted, then the number is a solution; otherwise, it is not a solution.
For example, if you have the inequality 2x + 3 > 7 and you want to check if the number 2 is a solution, you substitute 2 for x in the inequality: 2(2) + 3 > 7. Simplifying, you get 4 + 3 > 7, which is true. Therefore, the number 2 is a solution to the inequality.
