Question 685725
Four years from now, Daisy will be twice as old as Libeth. Six Years ago she was four times as old as her. Find their present ages.
----
Equations:
d+4 = 2(L+4)
d-6 = 4(L-6)
-----------------
Rearrange:
d - 2L = 4
d - 4L = -18
---
Subtract and solve for "L":
2L = 22
Libeth = 11 years 
========================
Solve for "d" using d -2L = 4
d -22 = 4
Daisey = 26 years
========================
