2. Create the function files det2 and det3 shown in the Week 5 PowerPoint slides (Page 15) Then write a script which accesses det3 to solve the equations ax + by + cz=k! dx+ey + fz = k2 gx + hy + iz = k3 Verify by solving the simultaneous equations 3x+2y+ z= 5 -x+5y -2z= -3 4x-7y + 3z= 10 Start your script with the following (fill in the blanks): a- 3; b 2; k1 = 5; det = det3( a, b, c,- detx = det3(k 1, b, c, ); dety = detz- x = detx / det, y , z= Finally, have your script verify the solution by substituting the values of x, y and z back into the equations
