I ended up using Gausian Elemination for the assignment and I got the same values. I know that people in the class have used the substitution method but substituiton is just impracticle and I don't have enough patients.
Thanks for all the help and ideas on how to do it

Hey I have just looked on the TI site and found a poly nomial simultaneous equation solver and found these values. Can you tell me if you got the same? I got A=3, B=2, C=2 and D=-1. I dare say the teacher will want me to show working so the only thing I could really do is spend a nice long day...
Hi
I am doing integration work in maths c. I have simplified the equation using long division however when I equated the answers, i got 4 simultaneous equations with 4 variables.
My equations are:
A + C = 5
A + B + 4C + D = 12
-A -B + 4C + 4D = -1
2A + B + 4D = 4
Can this be done?
The maximum will be found when the gradient function = 0. I found the gradient function using the product rule as y'=-x²+3x².Ln(1/x). Then when 0=-x²+3x².Ln(1/x) x= 0.7165. How ever it says in terms of e and this is where i get really stuck. I am drawing a blank on this one
Hi I am new on the forums here. I am having troube with my maths assignment. It says to find the maximum value of y= kx³ . ln(1/x) where k is a positive constant. I am also told to find the value of x, in terms of e. I am really struggling and any help would be appreciated.
Thanks in advance...
