Answer:

3:3:2:3

Step-by-step explanation:

b/a = 2/3 = b is 2 a is 3

c/b = 2/3 = c is 2 b is 3

d/c=2/3 = d is 2 c is 3

All you have to do to solve this question is to lay out all the variables and see which number matches with which.

Answer:

might be c

Step-by-step explanation:

a − b/c − d = 2 and a − c/b − d = 3 will hold for any values of a, b, c and d as long as

b≠0; c≠0

b/c − c/b = 1

and

a − d = 2 + b/c

If you let x = b/c, b/c − c/b = 1 becomes x − 1/x = 1

⇒ x2 − x − 1 = 0

⇒ x = 1.618 or  x =−0.618.

So

b/c = 1.618 or b/c =−0.618 is required.

The values of a, b, c and d are arbitrary subjected to

b/c = 1.618 or b/c =−0.618 and a − d = 2 + b/c.

Let c and d be the free variables, and let x = d/c then

a − d/b − c = (1 − c/b)x + 2 + c/b
