Solving Linear Equations and Systems

Solve linear equations and systems with reasoning, connect algebra steps to structure, and interpret solutions in context.

📋 What You'll Learn

  1. 1 Solve one-variable linear equations, including equations with variables on both sides
  2. 2 Recognize cases with one solution, no solution, or infinitely many solutions
  3. 3 Solve systems of linear equations by graphing, substitution, and elimination
  4. 4 Interpret equation and system solutions in real contexts
