text: If we read the book at a speed of 15 pages a day, we read it 3 days before we read it at a speed of 10 pages per day. If I read at 6 pages per day, how many days will I read the book?
  
  Result
  
  x =  15 d

  #### To solve this example are needed these knowledge from mathematics:
  
  Do you have a linear equation or system of equations and looking for its solution? Or do you have quadratic equation? Most natural application of trigonometry and trigonometric functions is a calculation of the triangles. Common and less common calculations of different types of triangles offers our triangle calculator. Word trigonometry comes from Greek and literally means triangle calculation.
