Hi there...
If you know that "(a+b)=84".
And you know that "((a/2)-(b/3))" equals a difference of "12".
You could then say that "(a/2)=((b/3)+12)".
Which equals "24" on both sides.
That in turn means that if "(a/2)" equals "24" then "a" must equal "48".
And if "(a+b)=84", that means that "b=(84-48)" equals "36".
Just to do a quick check...
"((a/2)-(b/3))" = "((48/2)-(36/3))"
That should equal "12", if not check your math.
Because if "((a/2)-((b/3)+12))" is correct, that in turn means that "((48/2)-((36/3)+12))" should equal "0".
I hope that helped a bit?
Kind regards
