Sorry, glanced up at the wrong name while writing my answer. Fixed.

$y$ is $7$, not $5$. But you did beat me to the other letters by a bit.

@DanielV See 2 comments up, 2 minutes before your comment. "Let me check $total=RHS$." :)

@user144808 I meant missing from my formula, not your question. ;-)

Yep, None of those 31 satisfy uniqueness. (For $total=45$. Let me check $total=RHS$.)

@DanielV The output is basically just a text string (display wise). There may be functions that would do that, but I'm still new to Mathematica. The fastest way for me to try that would be to dump it into Excel. (But the long time makes me think none of those 31 satisfy the uniqueness condition.)

@user144808 Hmm, with the 36 inequalities enforcing uniqueness it's taking too long to run, to expect a good solution. (For either interpretation of $total$.)

@Keith The sum of the RHS view gives 45 possibilities (before enforcing uniqueness). Give me a bit to encode the uniqueness.

@MattAllegro No, $E\in \{1,2\}$. I'll paste what I've got as an answer.

In all 31 cases, $C=1$. $E$ is either a $1$ or $2$ (with approximately equal likelihood).
