Solving System of Equations: Partial Fraction Decomposition Help

[khatche4]

Hello. I'm trying to solve a system of equations problem (for my Partial Fraction Decomposition problem)...

1 = -4 + 2B + 2C + D + E
3 = 4 - 2B + 2C - D + E
3 = -25 + 20B + 10C + 4D + 2E
5 = 25 - 20B + 10C - 4D + 2E

So that boils down to..

1 = 2C + E
3 = 2C + E
3 = 10C + 2E
5 = 10C + 2E
right??

I tried substitution, but that didn't work. Elimination doesn't work, either... So what else? I'm pretty sure you can do it graphically, but I can't remember...

Help, please! I'm doing this last minute (I know I shouldn't be, but I desperately need help!)

Something is not right here.

if you multiply your first equation by 5, you get: 5 = 10C + 5E

but your last equation is: 5 = 10C + 2E

So which is it? I think you may have made a mistake somewhere coming up with these equations.

What was the original "partial fractions" problem?
