Systems of linear equations using elimination

WebA line is an infinite number of solutions, but it's a more constrained set. Let's solve this set of linear equations. We've done this by elimination in the past. What I want to do is I want to introduce the idea of matrices. The matrices are really just arrays of numbers that are shorthand for this system of equations. Let me create a matrix here. WebSolve the following system of equations using Gaussian elimination. –3 x + 2 y – 6 z = 6 5 x + 7 y – 5 z = 6 x + 4 y – 2 z = 8 No equation is solved for a variable, so I'll have to do the multiplication-and-addition thing to simplify this system. In order to keep track of my work, I'll write down each step as I go.
