A solution to a linear equation in three variables — ax + by + cz = r — is a point in R3 that lies on the plane corresponding to ax + by + cz = r. So
Linear Equations in Two Variables - University of Utah
www.math.utah.eduA solution of a linear equation in two variables ax+by = r is a specific point in R2 such that when when the x-coordinate of the point is multiplied by a, and the y-coordinate of the point is multiplied by b, and those two numbers are added together, the answer equals r.
