I'm sorry but after writing this whole question in hebrew it turned out to be too much of a mess because of all the variables so I'm rewriting it in english.
I did not quite understand the matrix tool you suggested we use to save us the redundant manual labor.
Should we enter, for example in question 1, in the columns of:
x1-x4 the values of a-d
x5 the values of the bi
x6-x8 assign values of 0 or -1
for example would the following equality:
-2a+8b+10d-50=x6
be transalted to:
-2 8 0 10 -50 -1 0 0
Where the two last zeroes symbolize that x7,x8 do not take part in the equation and the -1 symbolizes the moving of x6 from the right side of the equation to the left side.
In addition I did not understand the meaning of:
sequence of pivot operations performed
Does it mean to state which is the entering variable and which is the exiting variable at each operation alongside showing the temp objective function?
Thanks
