GRE Linear Equations: A Guide to Efficient Problem Solving

Linear equations are a cornerstone of the GRE Quant section. While the on-screen calculator can help, true speed comes from mastering the algebraic methods. This guided path will teach you to translate and solve complex word problems efficiently.

Section 1: The Core Algebraic Engine

Building the Foundation: Solving for a Variable

Start by reinforcing the fundamental skill of isolating a variable. Our interactive balancer visually demonstrates the step-by-step process of solving any linear equation.

Core Methods: Solving Systems of Equations

Learn the two essential algebraic methods—Substitution and Elimination—which are often faster than using the calculator for finding a unique solution.

Section 2: GRE-Specific Applications

The Art of Translation: Building Equations

The GRE is famous for its word problems. This interactive guide teaches the crucial first step: deconstructing a problem statement and translating it into a solvable equation.

Application: Tackling Complex Scenarios

Move on to more complex GRE-style scenarios (like age or mixture problems) that require you to build and solve a complete system of two equations.

Strategy: Quantitative Comparison with Equations

Learn how to quickly compare two quantities involving linear equations without necessarily solving for a final value.
