Sara has twice as much money as Miguel. If she had $6 more. She would have 4/3 as much money as he has. How much money does each have now?

can't happen. How could she have less than twice as much if she had $6 more?
Check the problem. 
I solved the problem like that:
Sara: 2x
Miguel: x
2x+6 =4/3x
18/3 =4/3 6/3x
6 = 2/3x
x =  9
so Miguel = 9
Sara = 18
Is it correct? 
you know anybody with a negative age?
