What are Linear Equations in Two Variables? The linear equations in two variables are the equations in which each of the two variables is of the highest order (exponent) of 1 and may have one, none, or infinitely many solutions. The standard form of a two-variable linear equation is ax + by + c = 0 where x and y are the two variables.
Pair of linear equations in two variables refers to a system of two equations with two variables, typically x and y. These equations are linear, meaning that each variable is raised to the power of one and doesn’t involve any other operations like multiplication or division.
Learn about a class of equations in two variables that's called "linear equations." They are called that way because their graph is a line. These are the most basic and probably most useful equations you will ever know!
