Step-by-step explanation:

A linear equation is an equation in mathematics that can be written as displaystyle a 1x 1+ldots +a nx n+b=0,displaystyle a 1x 1+ldots +a nx n+b=0,displaystyle x 1,ldots,x nx 1,ldots,x n The coefficients are considered equation parameters and can be arbitrary expressions as long as they do not contain any of the variables. To produce a meaningful equation, the coefficients displaystyle a 1,ldots,a na 1, ldots, a n must not all be zero.

A linear equation can also be obtained by equating a linear polynomial over some field to zero and then taking the coefficients.

A linear equation's solutions form a line in the Euclidean plane, and every line can be viewed as the set of all solutions to a linear equation in two variables. This is the origin of the term linear, which is used to describe this type of equation. In general, the solutions of an n-variable linear equation form a hyperplane (a subspace of dimension n 1) in the Euclidean space of dimension n.

Linear equations appear frequently in all mathematics and their applications in physics and engineering, owing to the fact that non-linear systems are frequently well approximated by linear equations.
