A plus b plus c plus d plus e equals 30 where c plus e equals 14 and d equals b plus 1 and a equals 2b-1 and a plus c equals 10 find values of letters?

a+b+c+d+e = 30 (i)
c+e = 14 (ii)
d+b = 1 (iii)
a = 2b-1 (iv)
a+c = 10 (v)
By (i)-(ii)-(iii): a = 15
then, by (iv): b = 8
and by (v): c = -5
Also, b = 8 so by (iii): d = -7
and then by (i), e = 19
