Simplify the expression
X + 3/x - 5 = 56 - 3x / x2 - 13x + 40
For these types of problems, you need to isolate the unknown variable (move all the x's to one sude) by reversing all the operations in the questions. Remember, what you do to one side you must do to the other....
In this spcific question, I would first mulitply both sides by x-5/1
x+3/x-5=56-3x/x2-13x+40 ....turns ...
An expression is simplified. The solution is detailed and well presented. The response received a rating of "5" from the student who originally posted the question.
