Question 889984
Alan is six years older than Karen. The product of Allan's age three years from now and Karen's age three years ago is 324 years. find their present ages.
-----------------
Equations:
a = k + 6
(a+6)(k-3) = 324
---------
Substitute for "a" and solve for "k"::
(k+12)(k-3) = 324
k^2 + 9k - 360 = 0
------------------------
k= 15 (Karen's age now)
a = k+6 = 21 (Allan's age now)
