from our text book "Bittenger, M. L. & Beecher, J. A. (2007). Introductory and intermediate algebra (3rd ed.). Boston: PearsonAddison Wesley" can someone please help me with "Review examples 2, 3, and 4 in section 8.4 of the text.
•How does the author determine what the first equation should be? What about the second equation? Where do the numbers and variables come from. Try to find a pattern.
•How are these examples similar? How are they different?
•Find a problem in the text that is similar to examples 2, 3, and 4

We do not have the book or the equations.
