1.3 #1

Instead of using Guass Elimination for solving systems I've plugged it into the calculator.

Matrix A

[-8 4]

[14 -2]

Matrix B

[-4]

[12]

Then I've plugged in A^-1(B) resulting in a 2x1 matrix with the answer:

[1]

[1]

The first value corresponding to the x value and second to the y. (x=1, y=1)

I've found this to be true for all Guass Elimination problems. How to figured this out?

Let us consider the system of two equations below: 4x + 2y 14 2x -y-1 We can solve these equations using both methods. First, the substitution method. The process is as follows: In one of the equations, solve for one of the variables . te this expression for that variable into the other equation. This will leave an expression...
