Comparing Solutions: Linear Equations vs. Inequalities

What is the solution to the equation 5x + 3 = 18?

• x = 3

• x = 2

• x = 5

• x = 4

Which of the following values satisfies the inequality 5x + 3 < 18?

• x = 2

• x = 3

• x = 5

• x = 4

What is a common misunderstanding about solution sets for linear equations and inequalities?

• They both have the same solution set.

• They both have one solution set.

• They both have infinite solutions.

• They both have no solutions.

How can the solution set of the inequality 5x + 3 < 18 be represented?

• As a single number

• As an equation

• As an interval from negative infinity to 3

• As a point on a number line

Why is there an open circle on the number line representation of the inequality 5x + 3 < 18?

• Because the solution set is finite

• Because the solution set is empty

• Because 3 is not included in the solution set

• Because 3 is included in the solution set
