A+c=8
9(c-a)=54
c-a=6
c+a=8
2c=14, c=7, a=1
b+d=10
9(d-b)=72
d-b=8
d+b=10
2d=18, d=9, b=1
can someone point me in the right direction on this?
I factored the denominator to
so breaking it up I get
which turns into
which 'simplifies' to
which translates into the following system of equations
Assuming I did all this right, I'm not sure where to go. I'm used to at least one of those systems to actually be solvable... then you can run through the rest with substitution. In this case, I either made a mistake, or I need a bit of guidance on how to proceed.
*edit*
ok, so it occurred to me I could partially solve one of the above and then sub... so I solved 8 = A + C to be A = C- 8. I then subbed that into the third equation in the list... but end up with 54 = 72. So I'm thinking I must have screwed something up somewhere in there.
*edit again*
ok, so my math sucks. I was able to solve for C... I'm going to go through the rest now and see if I can figure it out. Pardon if I wasted anyone's time. I'll post back either way.
