Solution by inverse matrix method for JEE
Test of consistency and solution of simultaneous linear equations in two or three variables using matrices
Formula
If \(AX=B\) and \(A^{-1}\) exists, then \(X=A^{-1}B\).
Variables: \(A\): coefficient matrix, \(X\): variable column matrix, \(B\): constant column matrix.
Conditions: \(A\) must be square and non-singular.
Solving systems with unique solution.
