Please help me solve the following system of threeequations and discribe the methods that are being used to help me understand:
X + Y + Z = 6
2X - Y + 3Z = 8
3X - 2Y - Z = -17
Thank you!

1. What systems of equations can be solved by graphing or using substitution or elimination? Which method do you like best and why would it be different method. How would you answer this question?
2.Why graphing gives more visual of the problem and the elimination makes it easier to come up with the answer?

1. What is a system of equations?
2. Solve for X and Y in the following problems. Show all your work.
a. X + Y= 10 , 3X + Y = 12
b. 2X + 5Y = 19 , 3X + 3Y = 15
c. 4X + Y = 22 , 2X + 3Y = 16
d. 12X + Y = 174 , 8X - 2Y = 36
3. Suppose Bob owns 2,000 shares of Company X and 10,000 shares of Company Y

Solve for x and y in the following two sets of simultaneous equations:
4x-2y = 1 ......(i)
8x-4y = 1 ......(ii)
y = 2x + 3.......(i)
2y - 4x = 6 .....(ii)

To be efficient, under which conditions would you use graphing elimination or substitution? Provide an example.
The three methods of solving linear systems covered are substitution, elimination, and graphing.
There are examples posted on the solution field and in the attachment.

Answer the question and solve the problems below. Make sure you show all your work so you can get partial credit even if you get the final answer wrong.
1. Determine whether the lines will be perpendicular when graphed.
3x - 2y = 6
2x + 3y = 6

Please help with the following problems.
There are three methods to solving Linear Systemswith two Equations. They are the Graph method, the Elimination method, and the Substitution method. When would you use each method? What makes each method better than the other methods?

Matrices are the most common and effective way to solve systems of linear equations. However, not all systems of linear equations have unique solutions. Before spending time trying to solve a system, it is important to establish whether it in fact has a unique solution.
For this Discussion Board, provide an example of a matri
