I believe that the line from "Helen Grey" which suggests that Helen has an unrealistic sense of herself is the last option - Stoop from your cold height, Helen Grey. She is giving advice to herself that she should change because nobody will be there for her unless she does that.
Start of by writing 7x+1=50. Subtract 1 from both sides. You will get 50-1=49. Then you have 7x=49. Divide 7 on both sides. 7x/7. 49/7=7. X=7. Therefore x=7. Check your answer by plugging 7 into x. 7(7)=49+1=50. The answer checks out!
