A x B + C = D

If c = D what does b = to ?

To find the value of b in the equation A x B + C = D when c = D, you need to rearrange the equation and isolate the variable b. Here's how you can do it:

1. Start with the equation A x B + C = D.
2. Replace c with D to get A x B + D = D.
3. Now, subtract D from both sides of the equation to get A x B = 0.
4. To solve for B, divide both sides of the equation by A. This gives us B = 0 / A.
5. Since any number divided by 0 is undefined, we can say that b could be any value or undefined when c = D.

In conclusion, when c = D, the value of b could be any value or undefined.
