Problem Solving Using Linear Equations

Numerical: The ratio between the present ages of A and B is 5:3.

The ratio between A’s age 4 years ago and B’s age 4 years hence is 1:1.

These three types may cover cases of various types with different combination of ratios, fractions etc.

Before moving forth with the above given types of problems keep in mind these quick tips:- Case 1: Whole number form Numerical: The age of mother is thrice that of her daughter.

In this case both equations have "y" so let's try subtracting the whole second equation from the first: So now we know the lines cross at x=1.

The problem should list the Y- intercept, a starting amount of something and a slope, or a rate of change.You can also see:- Basic Probability Concepts for CAT Preparation Games and Tournaments for CAT Exam Logical Reasoning – Part 1 How to solve logical reasoning problems based on team selection and group formation?How to solve Logical Reasoning questions based on Ranking and Ordering Logical Reasoning Basics – How to solve coin picking / matchstick related problems?When the digits are reversed, the number is increased by 27. I know it’s an easy one but still you should read it at least twice. Rearranging and simplifying the second equation in the form “y – x = 3” and solving both the equations we get, x = 2 and y = 5 Now let’s check once are we getting the right answer if x = 2 and y = 5 then the original no. But, today in this blog, we will be focused on only one type of problems i.e. These problems are very confusing and the language is a bit complex and we end up usually making up errors in the formulation of the equation.So, I’ll discuss and try various different type of questions on this concept that will give you a thorough understanding of how to form Linear equations and solve them.Related Topics: More Algebra Word Problems How to solve Age Problems Involving A Single Person?

    For the word problems early in algebra, we generally want to set up our equations with one variable. Remember that we are in the chapter dealing with linear equations. Later in our study we will learn how to deal with multiple variable systems. For now, try to avoid using a second variable when setting up your equations. Video Examples on YouTube…
