six years ago, jim was four times as old as Fe. In four years, he would be twice as old as fe.How old are they now?

1 answer

4 years ago:
Fe : --- x
Jim: --- 4x

Now:
Fe = x+4
Jim = 4x+4

4 years from now:
Fe = x+8
Jim = 4x + 8

4x+8 = 2(x+8)
4x + 8 = 2x + 16
2x = 8
x = 4

Now, Fe is 8 and Jim is 20
