Hi all, I have a problem involving a rolling series of aggregate values for three successive years. I feel that I should be able to work out the values for the individual years but I can't work out how to do it and it is driving me slightly mad! A + B + C = 212.91 B + C + D = 277.62 C + D + E = 249.90 There are clearly common terms between pairs of equations but I can only get as far as rearranging the equations so that A=D  64.71 and B = E + 27.72 (I think!). Is there any way of working out what the actual values for A, B, C, D and E are  being percentages, they are all in the range 0100. Thanks in anticipation! Rob

You have five "unknowns", A, B, C, D, and E, but only three equations. The best you can do is solve for three of them in terms of the other two.
