Samael,

On the contrary, 2(x-y)=3(x-y) in mathematics given the information x=y
does in fact work out.  Since x and y are the same value (hence the equal
sign), then the value of x-y will be 0.  And all grade schools kids know
that any number multiplied times 0 is 0.  If this is looked upon from an
algebraic viewpoint, then 2(x-y)=3(x-y) can be divived by the common value
using standard postulates and theorems (learned in middle school/high
school algebra classes) which thereby results in 2 being equal to 3.  This
is standard everyday math and algebra.  Ask any professor of mathematics
if you do not believe me (be sure to show them this posting for an
unbiased answer).

Regards,

Robert
