A + B + C + D = 100

A * 4 = E ... A = E/4

B/4 = E ... B = 4E

C + 4 = E ... C = E - 4

D - 4 = E ... D = E + 4

(E/4) + (4E) + (E-4) + (E + 4) = 100

E/4 + 6E = 100 ... multiply by 4

E + 24E = 400

25E = 400

E = 400/25

E = 16 <===

A = E/4 = 16/4 = 4

B = 4E = 4 (16) = 64

C = E - 4 = 16 - 4 = 12

D = E + 4 = 16 + 4 = 20
