I am having a lot of trouble solving systems of equations by putting them in RREF.
I don't understand how you know what to do after each step. I keep working the same problem and I'm not getting anywhere.
The system is :
2x + y + 3z = 0
y + 3z = 5
x + 3/2y + 9/2z = 5
which would make my augmented matrix:
2 1 3 :0
0 1 3 :5
1 3/2 9/2 :5
I've started it in so many ways, but then I go through steps and can't get anywhere.
Can someone please demonstrate a step-by-step way of getting this in RREF and if possible give some tips that explain the best way to do this? Thanks
