Question 189501
Let x=Steve's borther's age
    2x=Steve's age

x-4 = 4*(2x-4)

x-4 = 8x-16

7x=12

x=12/7 brother's age

2x=24/7 steve's age

There seems to be something missing in the problem.

Obviously, both brothers weren't even born 4 years ago so this can't be right.
But I believe the math is right for this one though.
