to translate the puzzle into something more easily readable.

variables A,B,C,D,E in integer space {1,2,3,4,5,6,7,8,9}
variable F in integer space {1,3,5,7,9}

where A<>B<>C<>D<>E<>F (non repeated digits)
A=B+4
C=F-1
D*10+E=A*F



solving....

A=B+4 would limit A to {5,6,7,8,9} and B to {1,2,3,4}
C=F-1 would limit C to {2,4,6,8} and F to {3,5,7,9}

E is basically free to be any digit.
E=A*F-D*10
