Group Title
Part 1: Explain, in complete sentences, which method you would use to solve the following system of equations. (1 point)
Part 2: Explain why you chose that method (1 point)
Part 3: Provide the solution to the system. (2 points)
x – 2y + z = 0
2x – 3y – 4z = –9
x + 2y – 5z = 0
1. I used elimination method
2. I used it cause it's easier than the rest.
3. I got ((97/8,10/3,23/18)
Can anyone doublecheck my solution?

Yeah I will also prefer elimination here..

Reason is: The first and third equation consists same x and 2y so that they can be cancelled out by just addition or subtraction..

Add first and third equation you will get: 2x  4z = 0 2x = 4z 1 Now multiply first equation with 3 and second equation by 2: 3x – 6y + 3z = 0 4x – 6y – 8z = –18 Now subtract them: x + 11z = 18 2z + 11z = 18 9z = 18 z = 2

K I see how you got z, and I realize x=4 correct?

x = 2z if z = 2 then surely x will be 4..

You can verify your answer.. See you got 4, 3 and 2, Just plug in these values in the equation given and check whether they are coming equal.. Like for first: x – 2y + z = 0 4  2(3) + 2 = 0 6  6 = 0 0 = 0 This means your answer is correct.. Now similarly put in second and third you will get 0 in each case.. This is how we verify our answers..
