In Graphical Method we will be drawing graphs of two equations and intersection point is called the solution of the graph. We all know that a graphical representation of a linear equation in two ...

Some important points to revise from the chapter are: • An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in ...

What is a linear equation? Linear equations are frequently used to compute rates such as speed, time and distance problems. As a standard form of a linear equation in one-variable, this rule has the ...

A solution of this system is a list of values for the \(x_i\)s such that when we substitute them into (2.2), the equation holds. A system of linear equations is consistent if it has a solution, ...
