A linear equation is a linear function that shows what one value is equal to. A is the 3x3 matrix of x y and z coefficients. Check the equation for varying terms and constant terms.
In order to do this you may have to subtract or add the numbers you want to move from both sides.
So lets say I had the equation 5-- a big fat 5 5x equals 20. Integrate both sides make sure you properly deal with. Multiply the equation with the LCM of the denominator Step 4. Then as shown on the Inverse of a Matrix page the solution is this.
