My way of solving question will always refer back to the basics explained previously so that students can make the connect between basics and application of them. Let’s now start about the Linear Equations in Two Variable: In previous classes we have studied linear equations in one variable. In case of two variable equation can be put in the form of ax + by + c = 0 where a, b and c all are real numbers and a, b can not be zero. Many real life problems we cam solve through linear equations in two variables. Here we will learn about the basics and solve the questions given in our exercises. We learned how to plot them on the cartesian plane. We learned lines parallel to x and y axis. In this class we will learn to solve some advance problems in many other different methods: Graphical Method of Solving pair of linear equations Algebraic method of Solving pair of linear equations Substitution Method Elimination Method Cross Multiplication Method Equation reducible to a pair of linear equations in two variables Questions and answers Mathsphy provides unconventional and a better way of learning maths.
