I’m assuming you don’t need help with this anymore since your test was two weeks ago, but this is basically an addition table, so you can set up all kinds of equations (such as x+4=1) and use that solve for whatever you want. Please remember that we have office hours and private tutoring for the truly urgent questions; there are a lot of students using this free service, and when you post here, you have to accept the fact that it could take a while to get your answer..

Hi,

I stumbled across this question when I was reading through the posts. I did not understand this problem. Is there a diagram that should accompany this?


Could someone help me please?

i think the original poster made a diagram that was adequate. was there something you didn't get about my explanation?

No the problem was that I just could not see the diagram that is supposed to go with this question.

okay, it's this 4x4 grid the original poster wrote:

+ x y z
4 1 -5 m
e 7 n 10
f 2 -4 5

it may help you see it better if you make a 4x4 grid of empty squares on your paper and fill in the pieces i copied above. that should make things easier to see because then it will all be aligned properly. does this help?
