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? How are these examples similar? How are they different? Find a problem in the text that uses elimination method to solve a system of equations. Post the problem for your classmates to solve.
Blending Flower Seeds. Tara’s website, Garden Edibles, specializes in the sale of herbs and flowers for colorful meals and garnishes. Tara sells packets of nasturtium seeds for $0.95 each and packets of Johnny-jumpup seeds for $1.43 each.

...................................................When solving a problem with three variables using a system with three equations that are called an ordered triple, I would use an extension of the elimination method. I would do this by going from three equations (eliminating a variable) to two equations (eliminating the same variable from any other two equations) to one equ
