Study Notes

Properties of Equality and Inequality

Addition Property of Equality: Adding the same number to both sides keeps the equation balanced.
Addition Property of Inequality: Adding the same number to both sides preserves the truth of the inequality.
Division Property of Equality: Dividing both sides by a non-zero number maintains the equality.
Division Property of Inequality: Dividing both sides by a negative number requires reversing the inequality symbol.
Multiplication Property of Equality: Multiplying both sides by a non-zero number keeps the equation equal.
Multiplication Property of Inequality: Multiplying both sides by a negative number necessitates reversing the inequality symbol.
Subtraction Property of Equality: Subtracting the same number from both sides retains the balance of the equation.
Subtraction Property of Inequality: Subtracting the same number from both sides does not affect the truth of the inequality.

Definitions of Key Terms

Coefficient: The numerical factor that appears in front of a variable in an algebraic term.
Equation: A mathematical statement that asserts the equality of two expressions via an equals sign.
Equivalent Equation: Multiple equations that have identical solutions.
Inequality: A statement comparing two quantities using signs for less than, greater than, or their equivalents, rather than an equals sign.
Solution: A value assigned to a variable that makes an equation or inequality true; for example, in the equation 12 = x + 7, the solution is x = 5.

Types of Equations and Inequalities

Two-step Equation: An equation that involves two distinct mathematical operations to solve.
Two-step Inequality: An inequality that requires two operations for resolution.
