I should really know how to solve this seeing as I will be taking Cal II next semester...so this is kind of embarrassing, but I just keep getting stuck for some reason.

$\displaystyle \frac{-5}{4}=\frac{29}{4}+c+d$

$\displaystyle 404=432+4c+d$

Here is what I have until the point where I get stuck...

$\displaystyle \frac{-5}{4}*\frac{4}{1}=\frac{4}{1}*(\frac{29}{4}+c+d)$

$\displaystyle -5=29+4c+4d$

$\displaystyle \frac{-34}{4d}=4c$

$\displaystyle 404=432+4c+d$

$\displaystyle -28=4c+d$

$\displaystyle -28=\frac{-34}{4d}+d$

Here is where I start getting myself all messed up, any hints on what step to take next?
