- Express the system of linear equations in matrix form: a_{1}x + b_{1}y + c_{1}z = d_{1}, a_{2}x + b_{2}y + c_{2}z = d_{2} and a_{3}x + b_{3}y + c_{3}z = d_{3}
- Write the conditions for a solution of a system of linear equations AX = B.
- Write the given system of linear equations in matrix form. 2x – 3y = 1, x + 3z = 11 and x + 2y + z = 7.
- Find whether the system of linear equation has a unique solution or not. 5x – 10y = 4 and x – 2y = 8.
