Question 1163075
.


Why don't you create it on your own ?



Traditionally, such assignments are considered as the most simple in Algebra,


and it is expected that &nbsp;&nbsp;<U>every beginner student</U> &nbsp;&nbsp;<U>can do it</U> &nbsp;&nbsp;<U>on his or her own</U>,

without asking for help from outside.



But if you have difficulties in it, &nbsp;then could you tell, &nbsp;please, &nbsp;which precisely step is the most difficult for you ?
