thank you so much! would you be willing to explain this one?
x-y=2
-2x+2y=5

here is one...
2x-y+5z=24
y+2z=4
z=6

for using back-substitution

you are incredible thank you!

You're welcome

May i ask you what the R stands for

R stands for the row
So R1 means "row 1", R2 means "row 2", and R3 means "row 3"

okay so how did you determine subtract row 3- 3 by row1

okay can you tell me what you get for this one then...
6y+4z=-18
3x+3y = 9
2x -z =12

using the same method of row reduction or some other method?

row reduction :)

alright thanks, one sec

sure whats the problem

same thing so solving by row operations :)... its
x-2y+5z=2
4x -z=0

so the answer is consistent and dependent or x = 79z - 30
sorry I am a little confused haha

That makes sense! Thank you again! I appreciate all your help!

You're welcome, glad it's all clicking.
