A x 4 = E B ÷ 4 = E C + 4 = E D - 4 = E & A + B + C + D = 100 Challenge what is the value of E ?

Respuesta :

SJ2006

4A = E , A=E/4-----(1)

B/4=E , B=4E-------(2)

C+4=E, C=E-4------(3)

D-4=E, D=E+4------(4)

Substitute all values in 5th equation,

A+B+C+D=100  =  E/4 + 4E + E-4+ E+4 =100

 E/4 + 6E = 100

25E = 400

E=16 ANS....
