If ab = c - d, which of the following is an expression for d in terms of a, b, and c?

horsena [70]

ANSWER

$d = - ab + c$

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

$d = - ab + c$
