Does a change in one variable cause a change in anther variable?

Supplemental: If there are different variables on two sides of an equation, a change in either variable will inevitably change the variable on the other side to make the equation true. Example: A + B = C, where A = 5 and B = 6, C = 12. If A = 7 and B = 6, C changes to 13. As you can see, changing A to 7 from 5 changed C, but not B. The good rule of thumb being, if one side changes, the other side does as well. -Jonathan C. Holcomb _____________________________________________________________________________
