Answer:
I think it is -5,-5
Step-by-step explanation:
because it started at negative 5 qurdent two and it ends at in qurdent four at -5
a= 6-2b-3c
then put that equation inside the first one and then the second one
you get -6*(6-2b-3c)+2b-3c=23
and 5*(6-2b-3c)+4b-3c=-12
14b-15c=59
14b-18c=18/*(-1)
--------------------
3b=41
