Hi!

I'm new in this forum. Just wanna ask. How to solve this equation:

I have 3 value (A=13, B=3 and C=4.3333)

The eqution is: 13 / 3 = 4.3333

But when 4.3333 * 3 = 12.9999. How I'm suppose to tell the computer that 12.9999 is equal to A? My problem is more complex than this example. This just an example to simplify my problem situation. Did anybody has an explanation to solve this problem? Thank You in advance for you.
