Question 1035326: I need help solving this matrice problem dealing with systems.
2x+4y=2
-3x+y=11
This is what I have so far.
2 4 2
-3 1 11
I multiplied the first row by 1/2 to get 1 in place of the 2 in first row.
So then I need to get a 0 at the bottom of the first column. I multiplied -3 by the first row and got -3 -6 and -3. I added the product here to the bottom row. This is where I think I got lost. In the original system there is a 1 on the bottom row second column. When I added the product I got -2, so I'm not sure from here how to finish solving.

2x+4y=2 -3x+y=11 This is what I have so far. 2 4 2 -3 1 11 I multiplied the first row by 1/2 to get 1 in place of the 2 in first row. -Correct. So then I need to get a 0 at the bottom of the first column. - Correct I multiplied -3 by the first row and got -3 -6 and -3. - Incorrect. Multiply by "3" (instead of "-3") and then add. You will be on the right track. I added the product here to the bottom row. This is where I think I got lost. In the original system there is a 1 on the bottom row second column. When I added the product I got -2, so I'm not sure from here how to finish solving?
