Ellis is one year younger than Dender. One-half of Ellis' age is three less than two-thirds Dender's age. Find their present ages.
------
Equations:
E = D -1
(1/2)E = (2/3)D -3
-------
Substitute for "E" and solve for "D"::
(1/2)(D-1) = (2/3)D - 3
-----
Multiply thru by 6 to get:
3D-3 = 4D - 18
D = 15 (Dender's age now)
---
E = D-1 = 14 (Ellis' age now
