Final answer:
To find the solution set for the inequality 5y < 20, divide both sides by 5 and simplify the equation. The solution set is all values of y that are less than 4.
Step-by-step explanation:
To find the solution set for the inequality 5y < 20, we need to isolate y. First, divide both sides of the inequality by 5: y < 20/5. This simplifies to y < 4.
The solution set for the inequality is all values of y that are less than 4. This can be represented as (-∞, 4).
For example, y = 3 is a valid solution since 3 is less than 4. However, y = 5 is not a valid solution as it is greater than 4.
