WebSep 17, 2024 · First, lets add the first and last equations together, and write the result as a new third equation. This gives us: b + g + r = 30 − 2 g + r = 0 2 g + 2 r = 30. A nice feature … 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!
