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:
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?
If you solved the equation your answer would be x(Miguel)=-9 and Sara=-18. There is no solution because you can't have a negative amount of money.
