Cameron's uncle is 3 times old as he is. 4 years ago, he was 4 times older. how old is cameron?

Let Cameron be x years old now.

-

Now:

Cameron = x

Uncle =3x

-

4 years ago:

Cameron = x - 4

Uncle = 3x - 4

-

4 years ago, Uncle is 4 times older:

3x - 4 = 4(x - 4)

-

Find x:

3x - 4 = 4(x - 4)

3x - 4 = 4x - 16

4x - 3x = 16 - 4

x = 12

-

Find the age:

Cameron = x = 12

-

Cameron is 12 years old now.
