Question 779214
James is twice as old as Keziah. Three years ago, James was thrice as old as Keziah. How old are James and Keziah now?
----
Equations:
j = 2k
j-3 = 3(k-3)
-----
Substitute for "j" and solve for "k":
2k-3 = 3k-9
k = 6 yrs (Keziah's age now)
------
Solve for "j":
j = 2k
j = 12 yrs (James's age now)
