I'm now finding Rayyan first had 204 marbles and Brian first had 306 marbles.
Needs rechecking... 

                INITIAL            THE CHANGE

Brian             b                 b-42

Rayyan            r                 r+60

system%28b%2F6=r%2F4%2Cb-42=r-60%29
.
.
.
system%28r=204%2Cb=306%29-------each of their initial marbles
