Answer 1

I hope this solution would help you.
THANKS

Answer 2

Let B has x number of marbles and A has y number of marbles.

According to the question, x-2=y+2
                                           ⇒x-y=4       [equation i]

Also, given in the question, x+3=2(y-3)
                                            ⇒x-2y=9   [equation ii]
 
 by solving the two equations we get,
                                       
                                        x=17
                                        y= 13 .... that is the answer.
