... equation is introduced to form a system of two linear equations. When asked to graph x + 2y = 8 and 4x – y = 5, a student in Mrs. Reed’s class produced the results found in page 3.1 Note: to graph these equations this student first solved each equation for y so that they could be graphed as function ...

... A square system is a system that has the same number of equations as it does variables. If the square coefficient matrix is invertible, then there is one unique solution to the system. Invertible Square Linear Systems: Let A be the coefficient matrix of a system of n linear equations in n variables ...

... Because we end up with 2 = 2 it means that we have infinitely many solutions. If we graphed the lines they would be overlapping. You may have noticed that the 2 equations were the same because the second one was exactly 2 times the first equation. There is an infinite combination of coordinates that ...

... x0 = Ax. Ignoring the fact that x is a vector and A is a matrix this looks like our most important DE: x0 = ax. 2. If we solve the original equation we’ll have found x and hence y = x0 . Conversely if we solve the matrix system we’ll have found both x and y. Since we already know the solution to the ...
