Well on my text book, the exercise is 7.4 (not relevant but w/e) and the question is "Form an equivalent equation to each of the following by performing the operation given in brackets." Now the first question. "x-4=1 (+7)" Note: the "x" is a pronumeral. I'm expected to hand this in tomorrow and I have no idea what to do so if someone can help me by explaining how to do it, I will be incredibly grateful. Thanks in advance.
