MATRIX METHOD
LANGUAGE BASED QUESTIONS (WORD PROBLEMS)
The inverse matrix method is one technique for solving a system of linear equations using matrices. Given a system of linear equations, Ax=b, where A is a square matrix of coefficients, x is a column vector of variables, and b is a column vector of constants, we can solve for x by using the inverse matrix of A. The inverse matrix of A is denoted by A^-1 and is defined such that A^-1A=AA^-1=I, where I is the identity matrix.
