I don't get this at all please help
7x - y + 7z = -10
8y+7z = 17
-7x+4y+6z = 6
I know i have to set something up like [a]^-1 [b] in the Ti but i am just having a ton of confusion here...
When i got to that point i was lost because it gave me these long decimals my TI-83 is damaged so i couldn't see the answer....is it possible you could show me the fraction in the three part form.
