I'm trying to combine two Census features, and my algebra is a bit rusty. I have a table with "Household Type" in 5 columns across the top and "Age of Householder" in three rows on the left. I have entered the total for every row and every column - now how do I calculate the value in each cell? I'm not sure this is possible because there may be more than one possible solution, but I'm hoping someone has an answer here. THANKS in advance for any guidance that can be offered.
