Overview
Unit description, learning objectives, and skills.
Unit 4 — Systems of Equations teaches you to solve two equations at once. You will use graphing, substitution, and elimination to find the point where two lines intersect, and apply systems to real-world problems involving mixtures, rates, and comparisons.

Skills You Will Master
Real-World Connection
Systems of equations model situations where two conditions must be true at the same time. A business owner who needs to know how many units to sell to break even is solving a system. A chemist mixing two solutions to hit a target concentration is solving a system. Even planning a road trip — balancing distance, speed, and time across two routes — uses the same logic. Mastering systems gives you the power to solve problems with multiple unknowns simultaneously, a skill used in economics, engineering, science, and everyday decision-making.
