Find the ratio of a to b
c/3d=a/e and c/d=b/e
Thank you :)

Step-by-step explanation

1.  

a = 0, b = 0, e!=0

3 a - b c d!=0, e = (3 a)/(3 a - b c d), a!=0

a = 0, b!=0, c = 0, e!=0

a = 0, b c!=0, d = 0, e!=0

2.

b = 0, c = 0, d!=0

b!=0, d = (e c)/b, c!=0

Some solutions I think they are right not sure tho :D
