So when solving linear systems with two variables we are really asking where the two lines will intersect.
The book begins with systems of linear equations then covers matrix algebra before taking up finite dimensional vector spaces in full generality.
V w between two vector spaces v and w is the set of all elements v of v for which lv 0 where 0 denotes the zero vector in wthat is in set builder notation.
For more advanced students a graph is displayed.

In mathematics and more specifically in linear algebra and functional analysis the kernel also known as null space or nullspace of a linear map l. The main changes apart from the usual improvements during a new edition are the number of exercises which has more than doubled new formatting including color printing new sections on product spaces quotient spaces duality and the chapter on operators on real vector spaces. This is the third edition of this well known introduction to linear algebra. Typically such a student will have taken calculus but this is not a prerequisite. As you can see the solution to the system is the coordinates of the point where the two lines intersect.

A first course in linear algebra is an introductory textbook designed for university sophomores and juniors. This course covers matrix theory and linear algebra emphasizing topics useful in other disciplines such as physics economics and social sciences natural sciences and engineering.
