1. Define group to which the task belongs (tasks for work, the movement, percent or others). It will allow to define the direction and formulas of the solution of a task.

2. Define the unknown who will need to be included in the equation. Designate her for X. If it is several unknown sizes, then take a task question for X.

3. Make task model. Transfer all problems of action described by words in the text to mathematical formulas. Make mathematical formulas through X, specifying as any given action belongs to unknown characteristic.

4. Work out the equation, having included in it all actions which are interconnected with unknown characteristic. The unknown - X will be a result of this equation.
