ANSWER


d = - ab + c


Step-by-step explanation


The given expression is


ab = c - d

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.


This means that, we need to isolate d on one side of the equation while all other terms are on the other side.



We subtract from both sides of the equation to obtain,



ab - c = - d



We now divide through by -1, to get,




- ab + c = d


Or



d = - ab + c


The topic is change of subject
