Math CentralQuandaries & Queries


Question from damien, a parent:

S x U - T = 44
T - U x S = 36
U + T - S = 7
U x U / S = 4

Hi Damien,

Are you sure that you have these equations correct? If you multiply the second equation by -1 it becomes

\[-T + U \times S = -36\]

which is

\[U \times S - T = -36.\]

This is inconsistent with the first equation and hence there are no numbers $S, T $ and $U$ that satisfy these equations.
