LO2 Solve systems of linear equations relevant to engineering applicationsusing matrix methods Task 2.0 2.1 determine the determinant of 3x3 matrix : 12 3 0-41 0 3 -1 2.2a d.¢ circuit comprises three closed loops. Applying kirchhoff’s laws to the closed loops gives the following equations for current flow in mA... 2x+3y -4 2=26 x- Sy 32 =-87 -7x+2y+6z=12 2.21represent the above linear vector equations in matrix form and use Gaussian eliminationta find thecurrents x.y8z . 2.22solve the system of equations in 2.2 using the inverse matrix method.

2.23Evaluate the matrix solutions using MatLab.
