A * 4=E B : 4=E C+4=E D-4=E and A+B+C+D=100 what is the value of E?

E is 16 i solved ot in my head but if you do the math it adds up Q. When E Q self - Is 16 Check A*4. 16/4=4 4*4 = 16 B/4. 16*4=64 64:4=16 C+4 16-4=12 12+4=16 D-4 16+4=20 20-4=16 A+B+C+D = 100 4+64+12+20 68+12+20 68+32 100=100 I hope the spacing is correct when you view this cus I wrote this via a phone so I dont know if the writing will distort
