A x 4 = E
B ÷ 4 = E
C + 4 = E
D - 4 = E

A+B+C+D=100
C+4=E and D-4=E. so, C+D=2E Then, A+B+2E=100
From first two equations, A=E/4 and B=4E
so, (E/4)+4E+2E=100
25E/4 = 100
25E = 400
E = 16.

Ax4=B÷4
then B=Ax4x4
B=16A
Ax4=C+4
then 4A-4=C
C=4A-4
Ax4=D-4
then D=4A+4
A+B+C+D=100
A+16A+4A-4+4A+4=100
25A=100
A=100÷25
A=4
Ax4=E
4×4=E
E=16
then B=Ax4x4
B=16A
Ax4=C+4
then 4A-4=C
C=4A-4
Ax4=D-4
then D=4A+4
A+B+C+D=100
A+16A+4A-4+4A+4=100
25A=100
A=100÷25
A=4
Ax4=E
4×4=E
E=16
just clarify how coming 25
A+16A+4A+4A=25A
