How do i find the values of a b c d and e??

SO if ........





A + B + C +D + E = 30





and





AB = DE %26amp; BC = CD





how do i find the values of ABCD and E???

How do i find the values of a b c d and e??
It is impossible; not enough information is given.





If BC = CD then B = D.





But if AB = DE and B = D then A = E.





So A + B + C + D + E = 30 becomes





2A + 2B + C = 30





But clearly infinitely many choices of A, B, C satisfy.





So, again, more information is needed to uniquely define A, B, C, D %26amp; E.
