Expert Solution
- The solution uses the basic knowledge of solving a non homogeneous system of equations, how to find rank of a matrix, what is an augmented matrix, How to apply row operations to reduce any matrix to an upper triangular matrix.
back substitution means
starting from last equation and finding the variable's value then
using that variable's value in 2nd equation and then solving the
first equation for the first variable.
