I haven't exactly understood whats your problem.

You want to find x? or where x belongs to?

it is a parametric equation.. for example: 2x-ax=3a+2 => x(2-a)=3a+2 => there are 2 cases. 1st case: 2-a=0, a=2

0x=8 there is no answer to this one...

2nd case: a=/2

=/ means if it isnt 2

x=(3a+2):(2-a)

so the answers are

there is no answer if a=2

if a=/2 x=(3a+2):(2-a)

in this equation the parameter is 'b'

dude you have 3 unknown parameters. x,b,y. what are you trying to find there?

True , you only have two equations and three unknown parameters.

we done this in high-school(greece) there are 2 ways to solve this prob from the beggining and go to the anwser or from the answer to the beggining if you wanna find the way

+ the answer is not finished you can make it more simple and xεR/{-1}
