i have homework about linear algebra(just started learning it) and i got the following question
"to the linear equation systerm :
x+6y-18z=0
-4x+5z=0
-3x+6y-13z=0
-2x-2y+z=0
1. there is infinite solutions
2. there is only trivial solution
"
and i need to check if two of the claims are true or wrong or if only one of them is true.
if i remember correctly when there is a zero row there is also infinite solutions but what i should do now? i need to try to reduce it to row echelon form and see what i get at the end? do i need to try to "clear" the first colume from all zero numbers? i don't know even how to begin solving this. i am really new to this and i will be really thankful for anyone who will tell me what to do and give me some more information.
