    When I derived mine, I didn't know of Cramer's rule then I was still in the early period of high school. But Cramer used Matrices to derive his. I used another method. lol

    Besides its not the same formular just like the general method for solving quadratic equations and the completing the square method are similar so is my formula and Cramer's.

    You are a savior. Thanks so much. No wonder you are rated 99. It was really motivating and encouraging

    Don't be fooled by rating numbers. Just keep that "can do and will do" spirit.
