Hello,
What you did is correct...

... and you found A by identifying the term in
to get A = 5, right?
<u>What about the other terms?</u>
<u />
We can then identify the like terms:
>>> term in 
A = 5
>>> term in x
-2A+3=B
>>> constant term
6 = 6
As we know that A=5 it means that B = -2*5-3=-13
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
