Method
HintS
In math you cannot add or subtract unlike terms
example 3 books + 4 books = 7 books
3 goats + 5 books can not be added together.
11 books - 5 yams can not be evaluated because they are not like terms
therefore 4/5 + w can not be added, next you collect like terms
when you move term across = or > sign, the operation sign of the term will change.
i.e negative change to positive and positive change to negative.
Let solve the question now
