Extracting the results from a 1x1 sym from maple

Hey,

i'm using Matlab R2013a with the Maple tool box. I want to let maple solve the symbolic expressions. I'm using the follwing line to send Maple the data:

solution = maple('{b = x^3/y, a = b*x, y = d+x},{x,y}')

The result is a 1x1 sym.

Now my question: How can i extract the single reults as e.g. a or b?

And is there a possibility to write sth like:

eq1 = x^3/y -b

eq2 = b*x-a

eq3 = d+x-y

solution = maple('{eq1 , eq2, eq3},{x,y}')

Regards
