As you can see my value for V1 is wrong. It should have been 80V 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.
On the line beginning with 'At V2:', you have Ix=4Ix+I2 => 0=5Ix+I2, but you should be subtracting Ix from both sides to yield 0=3Ix+I2. I didn't read any further.
Forget it. You don't want to know. It costs big money. However, there are a lot of free equation solvers on the web. When you acquire Maple, you don't just get an application program. You get a weapons system. Maple 15
PG1995, you should probably practise your algebra anyway - fix up the error in your working I pointed out & see if you get any closer to the correct answer.
