A system of linear equation has two or three equations with two or three variables. The elimination method of solving systems of equations is also called the addition method. The Elimination is one of the three methods to solve systems of linear equations in two variables, the other two being graphing and substitution method.
X = [x y] X = [ x y] The constant matrix is: B= [ 7 −3] B = [ 7 − 3] Thus, to solve a system AX =B A X = B, for X X, multiply both sides by the inverse of A A and we shall obtain the solution: X = (A−1)B X = ( A − 1) B. Provided the inverse (A−1) ( A − 1) exists, this formula will solve the system.
