As you can see my value for V1 is utterly wrong. It should have been 37.818V according to the answer given in the book. I have checked my equations several times but I found nothing wrong with them. Please help me with it. Many thanks for your help.
That means there was nothing wrong with the equations but the method I chose to solve them messed up the answer. I used Cramer's rule. But surprisingly there is nothing wrong with the Cramer's rule's application; I have checked it. Don't know what's going on. If you are familiar with the Cramer rule, then please have a look and let me know where I went wrong.
