Question 1099090

Jack is 2 times as old as Lacy. 7 years from now the sum of their ages will be 
59.How old are they now?
<pre>Seven years from now the sum of their ages will be 59, so currently, the sum of their ages is 59 - 2(7), or 59 - 14 = 45
With Lacy's age being L, Jack's is: 2L
We then get: L + 2L = 45
3L = 45
