Question from damien, a parent: solve: |
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.
