The linear equations are always presented in the form.
Such a form consists of the variables, i.e., ax + by + c = 0. The linear equations are always presented in the straight-line form. In the ax + by + c = 0, a, b, & c are the form of real numbers. And in it, a & b will never equal zero.
In comparison, x & y are the forms of two variables, and c is always present in the same form.
Linear equations
When we see the two sets of linear equations together, they are always considered a pair of linear equations. And both sets of equation x & y variables are different from each other.
Solving methods of the equation
Substitution method.
Elimination method.
Cross multiplication method
Solutions of linear equations
When we see the linear equation in one variable, there is always one solution.
And in the linear equation of two variables, there are infinite types of solutions.
Many linear equations are there that consist of the solution (0,0).
The (0,0) solution equations are the equation that will normally pass with the origin.
Two-axis are presented on the graph, i.e., x and y.
