If you were to use the elimination method to solve the following system, choose the new system of equations that would result after the variable y is eliminated in the first and second equations, then the second and third equations.
3x – y + 3z = 1
4x + y – 6z = 3
4x – 2y + 3z = –3
7x – 3z = 4
12x – 9z = 3
7x – 3z = 4
4x – 6z = 3
3x + 3z = 1
12x – 9z = 3
3x + 3z = 1
4x – 6z = 3

I know it's either C/D, cause 3x+3z=1 is what you get when you eliminate y from 1st/2nd equation.

nvm other way around. It's A/B

Cause you get 7x3z=4 not what I said earlier.

Now, you multiply the second equation by 2 and then add equation 1 and 2.

Now multiply second equation by 2 and then add second and third equation and let us see what you get.

K I get it now :) It's A cause you get 12x9z=3. Was just a little confused about it.
