Simple question

[Guest]

This is a table:

+/ x y z
4 1 -5 m

e 7 n 10

f 2 -4 5


What is the result of the sum of m+n? an how do you get this result?

Thank you so much for your help

Does your table look something like the following?


. . . . .\(\displaystyle \large{\begin{array}{|c|ccc|}\hline\\+&x&y&z\\\hline\\4&1&-5&m\\e&7&n&10\\f&2&-4&5\\\hline\end{array}}\)


Are you given values for the other variables, or is that part of the exercise, finding those values as well?

If the latter, then I would start with the first column. If x + 4 = 1, then what is the value of x? With that value of x, if x + e = 7, what is the value of e? And so forth.
