Question:
i) 2) Solve the given system of equations by determinants.Evaluate the determinants by expansion by minors
i)
ii) Thank for your help and can you show me the working. Thank you sir Hi,You can evaluate a determinant using minors along any row or column. Looking at your determinant Now you need to expand each of the 4x4 determinants. Again I would expand along the second row in each case. This will give you six, 3x3 determinants. Expanding each, using minirs along a row or column wil give 2x2 determinants which you can evaluate. Cheers,Harley
