Web2 Systems of linear equations Matrices first arose from trying to solve systems of linear equations. Such problems go back to the very earliest recorded instances of mathematical activity. A Babylonian tablet from around 300 BC states the following problem1: There are two fields whose total area is 1800 square yards.

We can write this: like this: AX = B where 1. A is the 3x3 matrix of x, y and z coefficients 2. X is x, y and z, and 3. B is 6, −4 and 27 Then (as shown on the Inverse of a Matrixpage) the solution is this: X = A-1B What does that mean? It means that we can find the values of x, y and z (the X matrix) by multiplying the … See more One of the last examples on Systems of Linear Equationswas this one: We then went on to solve it using "elimination" ... but we can solve it using Matrices! Using Matrices makes life … See more OK. A Matrix is an array of numbers, right? A Matrix Well, think about the equations: They could be turned into a table of numbers like this: We … See more For fun (and to help you learn), let us do this all again, but put matrix "X" first. I want to show you this way, because many people think the solution above is so neat it must be the only way. So we will solve it like this: XA = B And … See more WebSolve system of linear equations, using matrix method 5 x + 2 y = 4, 7 x + 3 y = 5. Medium.
