When the system of equations is given in the matrix form , then to write the equation we find the dot product of the variable matrix and the coefficient matrix , then equating it to the constant matrix will give the resultant matrix.
The system of equations in matrix form is given as,
The given system of equations in matrix form is,
Using dor product the resulting equations are,
therefore , the equations are,
Answer is given below (on video)
Substitution and elimination, and matrix methods such as the Gauss-Jordan method and Cramer's rule. Use each method at least once when solving the systems below. include solutions with nonreal complex number components. For systems with infinitely many solutions, write the solution set using an arbitrary variable.
