Final answer:
To solve an inequality, substitute the given values and apply algebraic rules. The inequality x + y < y doesn't hold for x = 2 and y = 3 because 5 is not less than 3.
Step-by-step explanation:
The student seems to be asking about how to approach a problem where x and y are given numerical values and how to understand inequalities with these variables. To solve an inequality, one must apply algebraic rules, keeping in mind that if you multiply or divide by a negative number, the direction of the inequality changes.
For example, if the problem is to solve the inequality x + y < y given that x = 2 and y = 3, we would substitute the given values into the inequality, resulting in 2 + 3 < 3. After simplifying, we see that 5 < 3 is not true, so the initial inequality does not hold for these given values.
