Top Videos on Linear Equations Quantitative Aptitude for CAT by PW

Linear Equations is an important part of algebra, where the way you set up an equation matters as much as the calculation itself. A word problem may require you to translate information into equations, while questions with two or three variables call for suitable solving methods.

PW's MBA Wallah videos cover equation formation, substitution, elimination, cross-multiplication, and CAT-level applications. You can use these lessons to understand the methods, practise worked examples, and revise the approaches needed for Quantitative Aptitude Syllabus and Questions Practice.

Video 1: Connect Linear Equation Word Problems with Quadratic Equations

This lesson on PW’s MBA Wallah begins with linear equation word problems and shows how algebraic statements connect with CAT-style applications. It then introduces quadratic equations, explaining their meaning, root conditions, and standard solving methods.

A CAT previous year question provides additional practice and shows how algebraic reasoning is applied to exam questions. You can use this video after revising basic algebra or when practising questions that involve translating information into equations.

The combination of word problems, quadratic equation concepts, and a previous year question helps you revisit related algebra topics and understand how they can be tested in Quantitative Aptitude.

Video 2: Learn Substitution, Elimination and Cross-Multiplication Methods

This lesson introduces Linear Equations and their forms involving one, two, and three variables. It explains how to isolate the variable in a single-variable equation and how to solve equations with two variables using substitution and elimination.

Cross-multiplication is also introduced, along with worked examples, checks, and word-based equation formation. You can follow the steps from setting up an equation to finding its solution.

This video is useful when you are learning these methods for the first time or need to revisit the correct sequence of steps before attempting CAT Quantitative Aptitude questions.

Video 3: Strengthen Algebra Concepts with an Extended Marathon Lecture

The Algebra Marathon lesson gives you extended teaching time on Linear Equations before moving to basic algebraic identities. The linear equation portion develops the main concepts in detail, while the identities section introduces related algebraic manipulation.

This format allows you to study connected algebra topics in one sitting rather than revisiting them separately. You can choose this lecture when you want more time with the concepts or need to connect Linear Equations with basic identities.

Use it during a focused study session to revisit the material before moving on to mixed CAT Quantitative Aptitude practice.

Video 4: Identify Common Traps in CAT-Level Linear Equation Questions

This lesson moves from the basics of Linear Equations to CAT-level applications. It covers one-variable equations, practice questions, equations with two variables, and an introduction to three-variable forms.

You will also study consistency and inconsistency, solving techniques, common traps, mistakes, and practice based on previous CAT trends. The examples help you revisit different equation types and consider which approach to use for each question.

Watch this video after learning the basic methods, particularly when you want to revise common errors and practise applying equation-solving techniques to CAT Quantitative Aptitude questions.

These PW videos cover equation formation, solving methods, related algebra concepts, and CAT-level applications. Start with the lesson that matches your current understanding, then use the practice-focused videos to revisit different question types.

Working through the examples and attempting similar questions independently can help you check your methods, recognise mistakes, and prepare for Linear Equations questions in CAT Quantitative Aptitude.
