I'm not exactly sure what specifically you are asking for in relationship to balancing equations, but I have some examples with working out so you can examine them and try to go through the steps with them.

Glycolysis, the first process in cell respiration, produces four ATP, but it uses two of the ATP molecules, therefore producing a net two ATP molecules. The process also yields two molecules of NADH.Glycolysis begins with glucose and breaks it down into two molecules of phosphoglyceraldehyde.
