well that's complicated it would properly take a long time to read this which you ruined 10 second so sorry
When you simplify, you are just taking the equation down to it's simplest form, not solving it. Evaluation involves actually solving the problem.
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
What is the difference between evaluating an expression?
Evaluating the expression
It is "evaluating".

It would be either evaluating or simplifying.
First tell me the expression, then I'll tell you what the first step is in simplifying it.
I suggest that the next step should be identifying "this" expression.
Evaluating the expression.
Evaluate
That is sometimes known as EVALUATING the expression.

That is called 'solving'.
