Do take some time to watch the video clips to see if the notion of balancing equation (concept) is clear to you.

You will be hearing words like "balancing",  "add/ subtract to both sides", "multiply/ divide both sides by". 
From now, we shall refrain from using words like layman operations like "moving", "cancelling", "changing the sign"

E.g. 1: Solve x + 35 = - 20



E.g. 2: Solve x  = 935



E.g. 3: Solve 9x - 8 = 73
