The Total solution for NCERT class 6-12
Examine the consistency of the system ofequations.
5x − y + 4z =5
2x + 3y + 5z =2
The given system of equations is:
5x − 2y + 6z =−1
This system of equations can be written in theform of AX = B, where
∴ A is non-singular.
Therefore, A−1 exists.
Hence, the given system of equations isconsistent.
