Question: How to isolate/solve expression symbolically when variables are defined?

So i have defined some variables example:

xb=1000
yb=2500

db=5321
eb=521
and i want to solve the following symbolically without maple taking into account the variables:
eb=ab*yb*db*x

How do I force Maple to show the equation for the expression symbolically without unassigning the variables? I was thinking about local variables, but that would make the worksheet messy as the variables are used in other calculations.

Thank you.
