Linear equations on the GMAT are a test of logic as much as algebra. Success isn't just about finding 'x'; it's about efficiently translating complex scenarios and determining sufficiency. This guided path will teach you the core algebraic methods and the critical reasoning skills needed for a top GMAT Quant score.
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.
Goal: Isolate x.
Subtract 5 from both sides to remove the constant.
Divide both sides by 3 to isolate x.
Learn the two essential algebraic methods—Substitution and Elimination—for finding a unique solution when you have two variables and two equations.
The GMAT loves word problems. This interactive guide teaches the crucial first step: deconstructing a problem statement and translating it into a solvable equation.
Move on to more complex GMAT-style scenarios (like age or mixture problems) that require you to build and solve a complete system of two equations.
Master the most unique GMAT question type. Learn to analyze equations for sufficiency without needing to solve them, saving valuable time and avoiding common traps.
Value of x + y?
(1) $$ 3x + 2y = 24 $$
(2) $$ 27x + 18y = 216 $$
Divide (2) by 9: $$ 3x + 2y = 24 $$
It is the SAME equation! We don't have two unique equations.
Answer: (E)
