A slightly more complex illustration of the basic structure of problem solving.
The algebraic operations
of substitution and simplification 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 REQUESTRESPONSERESULT structure will solve any problem.
In the problem above, a simple concept is chosen for the basis of
the solution, namely, the whole is the sum of its parts.
Subproblems are indented for clear organization.
