The fifth problem is more interesting. It is immediately obvious that A=0, D=1

E=5; M=2; but B and D could be 3 and 5; 4 and 6; 6 and 8; 7 and 9, respectively.
 

G=1, A=0,

Т < 5

T+B=9. B=9-T

2*T=M

2*E=10+M=10+2*T. E=5+T

 
Arles:

Э=5

cannot = 5, as M cannot be =0, as A=0
 
sergeev:

G=1, A=0,

Т < 5

T+B=9. B=9-T

2*T=M

2*E=10+M=10+2*T. E=5+T

Thus, passing through the variants T=2, 3, 4 we find

Т=2 - cannot be, because it means B=E=7
Т=3 - cannot be, because it means B=M=6

we are left with
Т=4 - 4940+5940=10880

 
Right, I wrote it all wrong there
 
Arles:
That's right, I wrote it all down wrong.

Well, I've already made up my mind there.

 

It's easier to see:

mine would fit if M was the only one )). Well almost, there's still a little mistake I have

Admit it, you just have this textbook.
at the end are the answers. ))
