Union of two algebraic equations?

[Guest]

Say I have an equation:

a = b+c+e-d

and I want to find a [tex]\cup[/tex] b.

What would be the resulting equation?

Thanks - I only ask becuase I can't find this in any of my old books or anywhere online. Not sure if it is a linear problem but those didn't seem to work. Never seen this done before...

Thanks awesome people!

I do not see two equations.
Your example is union of two numbers.

To find the union of aUb we require two equations but you have given here only one equation so it is not possible to find the union of a and b.
Please provide the second equation also so that the solution cab be possible.
