Question

You figure that you will buy property many times and you endeavor to work out a formula that will tell you the price of the land and the price of the buildings any time.

So suppose the price for the land and buildings combined is S (for "sum") and the land costs D (for "difference") more than the buildings.

Then the price of the buildings is _????__ dollars and the price of the land is __???_ dollars.

Hint :Remember that in mathematics upper and lower case letters are distinct. So make sure that in your formulas you use upper case letters and , rather than lower case letters!

Answer 1

L + B = S
L - B = D
2L =S + D
L = (S+D)/2
(S+D)/2 + B = S
B = (S-D)/2

Answer 2

thanks, that makes sense and works out right!
