Linear equations are the foundation of the SAT Math section, forming the core of both the "Heart of Algebra" and "Passport to Advanced Math" domains. This guided path will teach you the essential skills, from solving systems to modeling real-world scenarios, ensuring you're prepared for test day.
Start with the fundamental skill: isolating a variable. Our interactive balancer visually demonstrates the step-by-step process of solving any linear equation.
Learn the two essential algebraic methods—Substitution and Elimination—for finding a unique solution when you have two variables and two equations.
The SAT loves word problems. This interactive guide teaches the crucial skill of deconstructing a problem statement and translating it into a solvable equation.
For many SAT questions, you don't need the final answer, just the correct equation. Practice identifying the 'rate of change' and 'starting value' to build the right model.
Master the visual side of linear equations. Learn how the solution to a system is the intersection of their graphs and how to use your calculator to find it instantly.
Understand the conditions for One Solution, No Solution, and Infinite Solutions. This concept is frequently tested on the SAT.
