Definition of linear equation:
A linear equation is a equation which can be written in the form ,
Also, a linear equation can also be written in two variables as of form,
The system of linear equation is when there are two or more than two linear equations are involved like,
So, we have two linear equation in two variables x and y.
Also, the linear equation has variables with the max power of variables as 1 then its a linear equation.
So, a system of linear equation with one or two variable can be written as two or more than two linear equations together.
Find the linear approximation of the function
Use L(x) to approximate the numbers
