If ab = c - d, which of the following is an expression for d in terms of a, b, and c? a. d = ab - c b. d = - ab + c c. d = c + ab d. d = - ab - c can you also tell what kind of question is this?

ANSWER



EXPLANATION

The given expression is



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,



We now divide through by -1, to get,
