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:
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?
