# The sum 17

The sum of three numbers is -1. If we multiply the second number by 2, third number by 3 and add them, we get 5. If we subtract the third number from the sum of first and second numbers, we get -1.

Answer the following:

Represent the above information algebraically. Convert the system of linear equations in matrix form. If the matrix formed by coefficients of variables is written by A, then find |A|. Find adj (A); where adjoint of A is the transpose of the matrix of the co factors. Find the numbers using matrix method.
