& A + B + C + D = 100

Challenge
*what is the value of E ?*

Answer 1

Ax4=E i.e. A=E/4................1
B/4=E i.e. B=4E...................2
C+4=E i.e. C=E-4.................3
D-4=E i.e. D=E+4...................4
ALSO A+B+C+D=100
i.e. E/4+4E+E-4+E+4=100
i.e. E+16E+4E-16+4E+16=400
i.e. 25E=400
i.e. E=16

Answer 2

e=16 is the answer for this
