Consider this system of simultaneous equations

$$\begin{array}{r@{~}c@{~}l l} 3x+5y-6z &=&2, & \textrm{(i)} \\ 5xy-10yz-6xz &=& -41, & \textrm{(ii)} \\ xyz&=&6. & \textrm{(iii)} \end{array}$$

Let a = 3x, b = 5y, c = -6z

Given that (x, y, z) is a solution to the original system of equations, determine all distinct possible values of x+y.

(Please list all the possible values)

The solutions (x,y,z) are (3,1,2), (-4,1,-3/2), and (5/3,9/2,2).  You can figure out the possible values of x + y from there.
