What is the formula to solve for d if b = cd?

To solve for ( d ) in the equation ( b = cd ), you want to isolate ( d ) on one side of the equation. To achieve this, you can divide both sides of the equation by ( c ), assuming ( c ) is not equal to zero, which simplifies the equation to:

[

\frac{b}{c} = d

]

This shows that ( d ) is equal to ( b ) divided by ( c ). This is the correct formula to find ( d ) when given ( b ) and ( c ).

The other options provided do not rearrange the original equation properly. In particular, dividing ( c ) by ( b ), adding ( b ) and ( c ), or subtracting ( c ) from ( b ) do not relate directly to isolating ( d ). Proper algebraic manipulation leads us to the correct relationship, confirming that ( d = \frac{b}{c} ) is indeed the correct formula.
