This solution illustrates the basic structure of problem solving.
The algebraic operations are done error free using
SureMath - the math software for 21st century problem solving.
The starting equation RESPONDS directly to what is
ASKED FOR and REQUESTS additional information.
The next step RESPONDS to the request.
Supplying the RESPONSE to the requesting equation
produces a RESULT.
The REQUEST-RESPONSE-RESULT structure will solve any problem.
The solution shown above is NOT a different method from the "answer book". Rather it displays what is actually done in solving a problem. Thus the problem solver and the reader are completely informed about the solution.
