Objectives: Solve linear equations, recall properties of equality.
Definitions:
Equality: Relationship of equal value.
Properties: Rules for balancing equations.
Equivalent Equations: Equations with the same solution.
Properties of Equality:
Addition Property: a − b = c → a = c + b.
Subtraction Property: a + b = c → a = c - b.
Multiplication Property: a = b → ac = bc (c ≠ 0).
Division Property: a = b, b ≠ 0 → a/b = c/b → a = c/b.
Distributive Property: a(b + c) = ab + ac.
Equation Types: Linear (e.g., 2x + 3 = 11) vs. Not Linear (e.g., 2x + 3y = 11).
Solving Steps: Simplify, isolate variable, and simplify again.
Application Problems: Involves real-world problems using algebraic equations such as hiker problems, coin problems, and more with varied solution strategies including quadratic equations and discriminants.
